I have an old Quadra 630 with Apple's TV tuner. I also borrowed an ixTV card from a friend to see how it works. Apple's TV is great, but works only on a Quadra 630. I don't have access to an XClaim TV, so you'll have to clue me in on the important issues. Audio never skips or stops, even when the system freezes up.
Video never stops, unless the video window is being dragged.
Even when the system freezes, video chugs right along. Video skips during processor-intensive tasks. There are very few options for video capture. Captured videos are of good size and quality, but suffer from minor jerkiness. Dear Customer, Thank you for your inquiry and interest in ATI products.
