Well then I won't try any more 9-pass encodes. As for setting the bitrates I assume that I would actually have to do some tweaking to CCE to achieve this instead of letting DVD-Rebuilder do all the work.

And although this is off topic, if anyone has any suggestions for Programs for Re-authoring DVD's (To remove Extra's and play with Menu's) asside from DVD-Shrink, could you PM me.

Thanks for the help guys
