If you were curious as to why Boxee suddenly became available for OS X 10.4 users, here's your sign. The underpinnings of the Apple TV are indeed based on Tiger, thus paving the way for Scott Davilla, a developer for the aTV-bootloader project, to announce that Boxee and XMBC can now be installed on Apple's set-top-box. In order to take advantage, you'll need the aTV Flash bootloader on a bootable USB drive, an Apple TV and the software in the links below. Currently, things are setup to run on Mac only, though PC / Linux versions are promised for next week. After signing up for a Boxee invite, jump on past the break for the step-by-step guide to getting this going.

Boxee, the open-source media streaming software that launched this summer, has always had a soft spot for Mac users. So soft, in fact, that it has just launched a new version that's completely compatible with OS X 10.4 (Tiger). The update also improves performance of multimedia library browsing and makes a few other minor changes / fixes sure to make heavy users smile. If you're still holding onto Tiger and want to know what the buzz is about, today's your lucky day.

Was it really 2006 when Linux lovers were sinking their gums into Neuros Technology's OSD? Two years later, we're finally seeing shipment of the OSD 2.0, which diverts quite significantly from the original in terms of design and ups the ante by adding support for encoding high-definition video at 720p in MPEG-4 and D1 resolution in the H.264 format. It's built around a Texas Instruments Davinci-based CPU module and a mini-ITX motherboard / enclosure, but rather than just being a very hackable consumer product, this one is described as a "super-reference design" by CEO Joe Born. You'll likely remember the WhereverTV, which is of course based on the OSD 2.0, and the firm has already landed another partner for the box in Hupla. For the individuals who just want an undisturbed unit, you can latch on now for $250.

Here lately, we've seen a number of questions flow in regarding TV tuners, so it makes sense that folks taking the plunge and building their own HTPC would want to know what flavor of software to mix in with it.

"I recently pieced together a pretty simple HTPC with an OTA TV tuner and I'm looking for the best PVR software to pair up with it. I'm currently running Windows XP MCE, but I could make the swap to Vista or Linux if the applications are good enough for either of those two. What would readers recommend for each operating system? Which one gives the least amount of hassle and works smoothly the majority of the time? Thanks!"

A pretty open-ended request, you see, but a valid one nonetheless. What's your favorite PVR software? Does Beyond TV have your heart? MythTV / SageTV the one(s) for you? Feel free to list the pros and cons of applications you've tried -- wouldn't want anyone to miss anything!

Got a burning question that you'd love to toss out for Engadget HD (or its readers) to take a look at? Tired of Google's blank stares when you ask for real-world experiences? Hit us up at ask at engadgethd dawt com and keep an eye on this space -- your inquiry could be next.

As the media streaming game heats up, quite a bit of focus is being placed on the software side. Take Boxee, for example -- this open-source application is designed to enable users to "control their media from a PC-connected TV," but in due time, it hopes to spread the program to set-top-boxes, cable company-issued HD DVRs, etc. Operating in quite the inverse manner, the system is slated to hit alpha next Monday, but it will only support Mac and Linux operating systems. Of course, a Windows-friendly version is due out soon, and given that it is based on XBMC, we have all ideas that it will be at least decently useful. As it stands, Boxee can support 1080p content, but DRM-laced material is still a no-go. The startup is hoping to round up a few alpha testers to get things moving in the right direction, and if you think you're the perfect candidate, tap the read link and get involved.

As a whole, it's hard to kvetch too much about Logitech's Harmony line of universal remotes, but as a devout hacker once told us, there's always room for improvement. Phil Dibowitz has been pursuing this project for months, and it looks as if a final release is at long last ready for mass distribution. Put simply, Concordance enables the Harmony family to be programmed in UNIX (which Logitech's software doesn't support) as well as in Windows and Linux. Furthermore, Phil states that the goal is to be "cross-platform," so Mac users should keep an eye out for future updates. Currently, the software supports every model save for the 890 and 1000, though both will hopefully be added in soon. Go on, give the read link a tap and get started -- just don't come crying to us if your "Watch TiVo" command starts opening the boss' garage door.
