Let's start with number two: I see you're using the b-frame reduction mode, and the 2nd pass error message tells me all I need to know.
Looking at the mencoder manpage I found this:
Quote:
vb_strategy=<0-1> (pass one only)

It appears that I missed that one and add vb_strategy to first and second pass, causing your problem. I will fix this in the next version. For now just don't use the adaptive b-frame setting when using lavc.
As for your first problem, I had to consult the manpage again but I'm afraid that's my fault, too. The me=0 option is the culprit.. mencoder uses me=1-4
I guess the error message in both cases would be there, but doesn't have either the word error or anything else I identify as an error in it.. otherwise MeGUI should halt immediately and not start subsequent jobs.
