My efforts to get assistance through the Nero website have been unsuccessful, but CCampbell appears to be very helpful, so here goes. I have an MCE P.C. and have been recording TV in dvr.ms format. I wanted to edit the programs and Nero appears to allow this. I edited. I burned. Burn completed and...I have been left with unplayable discs. Other items burned through Nero have been successful. I burned a dvd of a small file thru MCE successfully. Any thoughts? If you (or others) do respond, I will gladly paste the log here.
