Unfortunatly, that is one of the drawsbacks.
If you like to tinker, try creating some backups with the items you want removed, save them to your hard drive, then use VobBlanker to cut out unwanted material thats left over, again saving to the hard drive, rather than burning a disk.
As you progress, you can check your results using PowerDVD or a similar media player. After you are satisfied with the outcome, you can burn your final compilation to DVD.
Off topic in the Recode forum, but CloneDVD2, available from SlySoft, works very well for copying movie only, without leaving the blank screens.
It also has the option to copy movie only, with menus preserved. This is my favorite approach, as I like being able to select scenes.
There is a 21 day trial period. If you haven't tried it, you should check it out.
I use several backup utilities, and find they all have usefull features, not found in any single package.
