I have tried several tapes. From different tapes, and different times, it is always when the file is 730.1 MB. The VCR is a Daewoo VHS deck, it's fairly recent and seems to output a clean signal. I am sure the problem isn't the source.

As for modern machines, I don't have any way to encode video on my more modern ones.

I too prefer lossless compression, but am going with MPEG now because it;s what this card offers. I have an Aurora Fuse which records uncompressed motion JPEG, but it's got other problems.
