Actually I was copying from VCDs. And for once, google didn't help much :-(.
FYI, what I'm trying to do is to encode the movie from VCDs (which I dumped in bin/toc files using cdrdao) to divx. Unfortunately, mplayer/mencoder doesn't handle tracks in a bin file, so I'm forced to burn those bin files to a CD again, and encode them using mencoder. I've managed this for all the disks except this one for which the toc file is missing.
Messy, I know... I only wish I'd retained those original source disks. Thank you, all the same.
