Do NOT use MPEG-1 with analog sources, its incapable of storing interlaced content. Only use MPEG-2. Separate video+audio streams shouldn't be out of sync. The biggest problem with this era of hardware capture cards was the buggy drivers and software. Didn't matter if it was the Mac or Windows software, they both were horrible to deal with. I still have bad memories of fighting with Adobe Premiere and a miroVideo DC2000. Ugh.
