Some movies have 2 english soundtracks Dolby 5.1 and Stero. If you select only the Stero track you will get much better compression. Something to think about if you don't have surround sound like me. Just make sure you don't select the commentary track.
@taylor make sure you are looking into the future... You'll be pretty upset if in 4 or 5 years you get surround sound and can't use it.
I doubt that surround sound will go away that fast...... even the HD-DVD and Blu-Ray DVDs will are backward compatible with DVDs and the standard of surround sound. And even if you don't have a surround sound tv that audio channel breaks down to stereo or just plain audio that isn't stereo. So no problem for the immediate future...... but 100 yrs from now...... they will be complaining about their flying cars and their halogen replicators ......not real enough!!! LOL hell.... I remember back in elementary school (circa late 50s) that they were predicting flying cars by the year 2000!
LOL @IHoe about "flying cars in 2000", nice one buddy. Anyways, here's my tips for better compressions: <1> just backup the Main movie by itself <2> Main + Menu (AC3 5.1-ch English only) by using VobBlanker or PgcEdit to get rid of useless junks (FBI Warnings, Logos, Previews/Trailers, Advertise, Extras/Features, etc.) <3> encode with DVD-RB Pro + CCE SP 2.70 or ProCoder 2 Regards
