No, they don't make flawless copies. They only make near-flawless copies when coding to DVD, which has a much higher bitrate. For VCD, you don't have a lot of options, and mjpegtools is the best tool I've seen for low-bitrate MPEG1s. To get a good-quality VCD, just do mpeg2enc -f 1 -4 1 -2 1 -o FILENAME or, to go faster, just do mpeg2enc -f 1 -o FILENAME You will get about 60 minutes of video on 1 CD. The tweaking comes when you try to produce a Variable-bitrate stream, in which case you are NOT creating a VCD. In fact, the resulting stream probably can't be played back on most hardware decoders. Most of the auto-VCD creation tools for windows are actually hardware analog->firewire converters, that have MPEG-coding software attached. I've seen quite a bit of MPEG-coding software on both Macs and PCs, and I have to say that mjpegtools gives me the best output I've seen.
