[MPlayer-users] DVD encoding

[Van Leer]

Hi everybody,
I've been looking around for some informations about DVD encoding but I 
couldn't get enough. Is there a way, using mencoder, to reencode the 
main title of a DVD only a bit. Just enough to store into a 4.7Gb DVD-R.
The problem is that I have to backup a DVD onto a DVD-R but the main 
title itself is more than 4.7 Gb.
I would like to retain both italian and english 5.1 sound with subtitle too.
I've found that with dvd shrink I could remove other languages and 
reencode as well, the only drawback is that (AFAIK) the reencoding is 
only at fixed bitrate. Is it possible to prepare the movie track to be 
feed into dvdauthor with mencoder and a 2pass encoding?

Please let me know. I have those 7 Gb film on my HD and I would like to 
burn them soon.


Thank you all,
VanLeer.
