Interesting, try to change the value that was 0 back to 0, like this, maybe
that setting did that. It is good here with that changed, but let me know,
right now I'm just doing tests with cat/dd which probably Myth isn't going
to do well because it wouldn't understand that possibly if trying to check the
frames and GOPs to be normal (which actually in the Mpeg standard it isn't
really set how big gops have to be I think, seems they are really flexible like
this, it seems pretty crazy to me it's working as well as it is right now
(think that means it's a good codec).
