Tucked in between the "worst kept secret" PSP Go and motion control demos at its E3 press conference, Sony also revealed new content for the PlayStation Network video service, and the ability to download video directly to the PSP, no PS3 or PC intermediary needed. No word on when to expect the new content exactly, but it will include video from Showtime Networks, Starz, G4 & E!, Summit Entertainment, The Weinstein Company, HDNet & Magnolia Pictures, Anime Network, Media Blasters, Right Stuf's Nozomi Entertainment, Starz Media's Manga Entertainment, Toei Animation, Viz Media, WEP, UFC, TNA and Video Action Sports. Looks like Sony will have easy on the go access to video store content up and running before Microsoft gets its Zune integration act together, but whether that compares to 1080p instant streaming promises remains to be seen (Hint: first one with direct Hulu access wins, we're just saying, guys.) Check out Sony's trailer embedded after the break.

While you're kicking back and enjoying some HD content on a lazy Sunday it is easy to give little regard to the economics that make that HD content possible. Most don't care much about what makes the world go around, but if you've always wondered why there aren't more all-HD channels, this recent post over at Multichannel news is worth the read. Most notable is the challenges all-HD networks face including the fact that Nielsen doesn't even provide rating for them. If you're a big Mark Cuban fan you might also find it interesting as a number of his quotes are included like when he says "We really think that as our distribution continues to grow, we can dominate the demographic (13-34 males)."

Bad news for Mark Cuban, not only are his Dallas Mavericks out of the NBA Playoffs, but Time Warner Cable is dropping HDNet and HDNet Movies on all of its systems on May 31. Hopefully this doesn't mark the beginning of the end of the network MOJO HD-style, especially since we've heard of the network sliding onto new Comcast systems recently, but TWC PR director Robyn Watson doesn't seem optimistic, saying "being in HD is not enough." Ouch. Still, fans of Art Mann Presents and the like take heart, the "24x7 HD Network for men" MavTV is launching on the HD Xtra tier at the beginning of June.

The Super Bowl isn't even underway, and our HD gluttony is already warming up for March college basketball. Only a couple of years old, the College Basketball Invitational (CBI) has agreed to bring its 16 team bracket to HDNet in March. Normal folks might think that three basketball tournaments running simultaneously from the second half of March to the beginning of April -- the NCAA, NIT and CBI -- might be too much, but serious fans (or those unfortunate enough to have favorite teams spread across tournaments) know better. For those people, we suggest getting a hold of as many tuners as you can and buying Visine in bulk.

We're not so sure that we like the direction this might be headed in, but HDNet Fights has signed up with Ring Honor of Wrestling for content, including a weekly series. The professional wrestling promotion was founded in 2002, and with its Code of Honor rules, it was a step away from typical professional wrestling and towards pure catch wrestling, but it's professional wrestling still. We had hoped that HDNet Fights was going to establish itself as a smaller, but still viable alternative to UFC, but this move suggests otherwise. We know HDNet Fights needs to add content, but is there enough audience overlap between professional wrestling and other fight sports that this makes sense? MMA fans, let us know what you think -- does this move water down the brand?

Another month, another trip down memory lane comes to us courtesy HDNet's Concert Series. That lane is getting longer than we'd like to admit, as this Sunday "Cowboy Junkies: Trinity Revisited" will air live to mark the 20-year anniversary of the audiophile classic "The Trinity Session." We won't bother to count the number of copies of the recording that we've been through, or how many different formats (hint -- we used to call them "albums"), but we'll tune in at least for "Sweet Jane" one more time.

We'll admit we have just about every disc put out by The Cure during the 80s, but we're surprised to see them putting up a live show on HDNet's Concert Series this Sunday. It's HD, so that's a good excuse for us to break out the eyeliner and hairspray and dress up like it's Halloween a few days early while we check out the band on tour for its latest album, "4:13 Dream." Robert Smith looked pretty tired back when we saw him during the "Wish" tour some 16 years ago, so we're a little anxious about how HD will treat him now; but if there's one guy who knows how to lay on the makeup, it's him. Don't feel bad if you tune in and know all the words -- the sold out tour lets you know you're not alone.

Look, we know good and well your Halloween night is already booked solid, but that's not to say you can't start getting spooked out a few days beforehand. HDNet Movies is looking to set the tone this year by debuting the horror film Splinter two days prior to its theatrical release. The flick is the feature film debut from British director Toby Wilkins, and the press release even describes it as "an exhilarating ride of jolts and laughs, and a throw back to the classic creature features of the early '70s and '80s." Sounds like the perfect way to spend an 8:00PM time slot on October 29th, yeah?

Add two stations to Project Infinity, Comcast has -- after several years of battling -- signed up Mark Cuban's HDNet and HDNet Movies, plus a free video on-demand package. Specifics on when the channels should go live in your area weren't noted, only that the cable company plans to increase its carriage of the two networks over the next year. Hopefully Comcast subscribers will get a (non-bandwidth starved) peek at Dan Rather, HDNet Fights, early movie premieres and more before tru2way and switched digital video roll out, but we can't be sure.

Ready for another concert series from HDNet? This time around the 1080i, 5.1 surround series is titled Hard Drive HD and has been created in partnership with AOL Music. The idea is for concerts to air Sunday nights on HDNet, then Monday on AOL music when the show airs regularly starting in October. All 13 concerts come from the House of Blues in Atlantic City, the sneak peek coming July 13 at 8 p.m. features Good Charlotte, ahead of HDNet's usual Concert Series.

Rack up another collaboration for the MMA-centric HDNet Fights brand. The topsy turvy world of MMA has seen lots of M&A activity over the past year, which fits pretty well with HDNet Fights' come-one-come-all partnership attitude. Adrenaline MMA, formerly under the M-1 Global banner, will be bringing its first three cards to HDNet. The first event will be in Chicago on June 14, with a second show on September 6. Disappointingly, this agreement comes too late for those hoping to see top-ranked Fedor Emelianenko come to HDNet, as he split with M-1 before the restructuring; so any Emelianenko vs. Silvia matchup will have to be a cross-promotion. But like we said, it just might be possible in the "anything goes" operations of HDNet Fights.

Fledgling MMA player HDNet fights has signed up with an even fresher face in the MMA game, DREAM, to air six DREAM Japanese fight cards here in the US. The DREAM organization kicked things off in Japan on March 15, but don't confuse its newcomer status with a lack of experience; the organization looks an awful lot like K-1 HERO'S combined with the now-defunct PRIDE, right down to several of the fighters and staff (and apparently, an affinity for all caps). From the sound of things, DREAM is having a hard time getting off the ground in its home of Japan, so we're pretty sure HDNet was able to pick up the deal under some pretty favorable terms. Could HDNet Fights' take-all-comers approach get us some HD competition for the UFC over here? We certainly hope so.

On this week's podcast we got down a little bit on oval course racing, but if you want to check out a different take on the theme, tune in to HDNet on April 11th and 12th. For the sixth year, the network will be broadcasting the "Little 500" from Indiana University. It's an oval all right, but the event is all about fixed-gear single-speed bicycles with coaster brakes on a quarter-mile cinder track. No matter whether they're a "cutter" or a "frat boy," riders must use an event-provided bike with no mods and must make switches during the event. Think you were fast on that banana-seat Schwinn (complete with "are you kidding me" toptube-mounted gearshift) as a kid? Think again.

The All-for-Nots kick off a 24-city tour of America March 9, when their show premieres on HDNet at 7:45 p.m. A comedy series made up of 7-10 minute episodes, this fictional documentary -- sounds a lot like a Flight of the Conchords / The Office mash-up to us -- will serve as a lead in to the channel's Sunday Night Concert Series. EngadgetHD friend Mark Cuban thinks viewers will tune in via cellphone and Youtube networks where the episodes will be posted by its studio (Vuguru, notably founded by Michael Eisner's The Tornante Company), and catch up on the shorts in HD and 5.1 surround sound on the weekend. After quarterlife set a record for being yanked after one episode, we're not overly optimistic, but out of the ratings obsessed culture of network TV, maybe The AFN has a shot.

Sure, there's been plenty of WWE talk 'round these parts lately, but we're making sure MMA fanatics aren't left in the cold, either. Later this month, HDNet Fights will exclusively air the debut of Kim Couture, who, if you couldn't surmise, is the wife of famed MMA legend Randy "The Natural" Couture. The event is slated to take place at the Xtreme Couture Gym in Las Vegas, Nevada on February 29th directly after the network's LIVE IFL event. If that just seems too far away, feel free to catch Mrs. Couture (and her hubby) on Inside MMA this Friday at 9:30PM (also on HDNet).
