For the record, m2ts and vob are not even close to the same thing technically or otherwise. And MPG is a completely different container even further away from MPEG2-TS and MPEG2-PS. BRMPEG isn't a legit format name either. Renaming files will not change the container they are so that won't actually work unless it bullies a different demuxer into action, and in this case it won't. MeGUI and friends don't give a shit what your input format is when x264 doesn't support it and they don't include their own demuxers. x264 DOES support m2ts sorta. Anything else?
