can i at least hook that ---Cleveland steamer--- up to a computer?
Yes. Google it a bit and you should find drivers and codecs. Originally you needed WinDVD8 but I think now if you get the right codecs you can play it with any DVD software.
I've been reasearching this lately and it's not as straightforward as it seemed. The version of WinDVD 8 people were using had to be imported from Japan and originally didn't even work at anything above 540p resolution. Nowadays people are using PowerDVD Ultra for $100

and you can get full 1080p out of it, but only if your system meets HDCP requirements. Download
Cyberlink BD/HD Advisor to find out if your PC is going to be useable. You either need a fairly modern (fast) CPU or a video card with hardware HD support just to play the movies in addition to being HDCP compliant for full resolution.
When you plug the drive in for the first time XP will recognize it and can install the new drivers for you. Then you'll need to install the
Toshiba UDF 2.5 drivers (note: I can't vouch for the safety of this download although I have virus scanned it and have it running on my own system) and reboot. Now you should be able to browse the drive when you have a movie in the tray. From there you load up PowerDVD Ultra and you're done, probably.
The AVS forums have an enormous thread on this and it's hard to follow because they're also discussing using PowerDVD for Bluray playback, and a lot of people aparently have systems with both drives. So when they're talking about using one build of PDVD for this movie and a diffeent build for that movie it becomes hard to tell whether they're having problems with one format or the other, or both. A few comments here and there seem to imply that it's the Bluray movies that cause the problems.
I haven't tested this fully yet because I have an oddball dual video configuration that may or may not work so I'm trying to either get a definitive answer on that or find an "evaluation copy" I can test. Even if it works, $100 is a bit steep for video playback software. But then I've gone from zero HD-DVDs (in about 8 months of owning the player) to owning more HD-DVDs than DVDs in about a week, so maybe it's worth it to give my poor 360 a rest.
