First of all - I know the HD-DVD addon has been talked about and questioned to death; please just move on if you're sick of reading and don't feel like offering any help. That said....
I just picked up one of the xbox hd-dvd drives with the hope of using it with my computer. Running Windows XP (SP2), the "new hardware wizard" popped up when I plugged it in. While it did recognize it as a DVD drive, it wouldn't recognize HD-DVDs. After installing Toshiba's generic driver (thdudf.sys), my computer will now recognize HD-DVDs, and I can browse the contents of the disc. However, I still can't get any software to play them back. I've tried both PowerDVD 7.3 and 9.something, Ultra editions, and neither one will work. They just spin for a second, then flash "file mode" in the upper right corner for a second before going back to doing nothing. However, it will play regular DVDs just fine from the same drive.
Is there some obvious step I'm missing? Are there additional drivers I need to install? Different playback software? Also, I only have one HD-DVD at the moment - Nine Inch Nails' "Beside You In Time". Could it be that the disc itself is one of the ones that doesn't play nice with this setup? I've watched it on another one of these drives, connected to an xbox, so I know the disc itself works.
Any help would be most appreciated! Thanks!
