I have a PCI-X Hauppauge 1800 MCE which works awesome in Vista 64. I run Windows Beta 7 build 7000 with the same hardware and it works... but there's pretty significant distortion and interference lines on the image in Beta 7 media center. I figure its a driver problem or something that has yet to be handled, but I figured I'd ask if anyone knows of any issues. I know in Vista 64 I just got a new driver thru windows update, maybe one was released in Beta 7 but I haven't booted into it yet to check. Any ideas?
