Couple quick questions. First is there a difference between the Womble export file options (.mpg and .mpv) ? I had been exporting them as .mpv then later I noticed it somehow got changed to .mpg. I'm still getting a complete stream copy which is what I want but I just want to be sure which file type I should be saving as (if it matters).

Secondly when I import my movie file into DVDlab Pro it gives me a messages saying the file still has "open GOP's". Am I doing something wrong when exporting from Womble to get this message with the file in DVD lab Pro?
