I've been failing to do that, hence why I already have a couple of "broken"
DVD's. They still play but they have a lot of skipping. They skip 3 or 4
minutes of playtime due to scratches.
Not a big drama, they were cheap but it's kinda dumb to allow that to
happen and then having to buy a new DVD from the bestbuy. I teach my
daughter to take care of her stuff, and I know she's careful but once in a
while "accidents" happen and a DVD ends up on the floor under people's

was using dvdnav. On the remaining ripping commands I forgot to move to dvd

Interesting. The result is a VOB, not an M2V? Wow.

Wow, there's so much info on ffmpeg and mencoder on your message that it
will take me some time to digest.
I'll get back in a couple of days after I test all this.
Thanks a bunch, Miriam.
