It's a possibility but a little difficult. I try to explain ...
Fisrt we Compress and after we delete the bonus features.
A) for determinate the total of megs for DTOX
- Rip with DVDBackup
- Open the folder Video_ts
- Calculate the total Gigas of the Movie only (Normally all VTS_01.VOB)and
Calculate the total Gigas of the Rest (all bonus, extras...)
- Total of disc = 7 gigas
- Movie + Menu = 5 gigas
- Bonus = 2 gigas
you must have at final a VIDEO_TS folder of 4472 megs(4.36 Giga / DVD size) with menu and Movie. Here is the calcul.
The initial 5 gigas must be 4.36 after DTOX
87% is the proportion
87% of 7 giga (Total of disc) is 6.09 giga
For security it's better to increase a little this at 6 giga
convert in Megs (6*1024) 6144 megs
B) Open DTOX make "Full Disk" and user rate at 6144
Chose language and Start.
After that open the final VIDEO_TS and delete the Bonus/extra .VOB files
Get info for VIDEO_TS folder and Normally you have a folder less than
4.36 GB you can burn with Toast.
Note: for 2 hours of DTS sound you must count about 1GB and 400 MB for 5.1 Dolby D
Last but not least, it's work fine : you have all menu but if you try to access bonus/extras the menu block and you must touch the "Menu Touch" of remote to come back.
Sorry for my english and i hope i help you or someone else.
