searching may give you more specific answers, but im gonna throw my 2 cents in
if you convert to mpeg, expect to get 1 minute of video to 1 minute of audio, i e a 74 minute cd will hold 74 minutes of vcd video/audio. i dont think the version of
nero matters so much, just as long as it has vcd capabilities.
also, TMPGenc is the (free) standard for converting. try
