I solved the problem joining the files. the first one I did came out wonderul and ready to burn buuuut This particular file was in 5 parts @ 30 fps and I got them all joined. But when i play back the MPEG2 file is choppy. The same thing happened when I tried to playback the same source that was split in 7 parts @ 60 fps. Could it be the source that is bad? Is it something I am doing? Oh yes I am using iSkysoft MKV Converter to do the job. Like I said the first file worked beautifully but this one is so choppy.
