I converted a bunch of avi's to mpg with TMPGEnc. No errors from TMPGEnc, did it as Layer 1 MPG and all that jazz. Some of the files will burn fine with Nero, but some of them won't burn at all. When entering them into the compliation window, some get checked, and the others just enter and do not have a length associated with them. I figure this is some problem with the encoding process, but how can i fix this if i am going through TMPGEnc?
