Well, it almost worked, as BBmpeg had problems when muxing; but I found that muxing with TMPGenc itself is much better, so at last it worked completely. Besides, it's possible to select the "source range" option inside TMPGenc and solve the problem, although it's still very annoying.

I finally found it: after I had tried a conversion to *normal* VCD, and the problem had remained, I realized it was a media fault. I was using a CD-RW and maybe it didn't work at all, maybe it had been rewritten too many times (and not full erased), but when I burned the movie to a CD-R (a Maxell CD-R 74XL, if someone is interested) everything looked perfect!
