[HELP] can't start to encode, always waiting

[Selur]

i want to encode a merged VOB file,

Why are you merge vob files instead of opening the DVD?

Judging by the screenshots you took (a debug output would have been more informative) the length info of your merged vob file reports it as 45sec long, which is why the progress indication goes hay wire when the encoder reports it encodes way more frames then there should be.
However you merged your vob files into a single file it's not the proper way to do it and Hybrid is not designed to handle files with wrong/broken header information.
-> I would recommend to not use Hybrid or learn on how to merge vob files (if you need to) while making sure the created file has proper header information.
