If this has already been addressed in the forums, I am sorry I could not find anything

When I encode a 2.5hour DVD with FairUse split to two 700MB files, I end up with a 580MB file and 940MB file. This has occurred many times with different movies, whether I encode the two halves using batch processing (700mb each) or select '2 Output File Segments' (and a 1400mb file) makes no difference.

Any help is appreciated.
If nothing else works I can encode with CBR audio to 1400MB file and split with VDub.

Yeah I'll try and see if one pass changes it, it's just weird because I've never had any problems with file sizes encoding into a single movie in the past.. and it does this when i split the movie into two segments manually or automatically. Thanks tho.
