I have ATI-Wonder PCI and CPU 2,2GHz. I tested capturing (352x288) of composite VHS source (same part). The result =
TV player 2.0 from MMC 6.2 ... droping frames
VirtualDub 1.4.9. - the same - droping frames o the same part of video
Capure from Ulead Media Studio - NO dropped frames.

How to explain it?
