I rarely post. I think it's best to search through other peoples posts to find the solution to my problems. Sometimes I resolve my problems through deduction. However, I have pulled my hair out on the following problem: Nomatter what I use to burn my (encoded or backed up) - The media is "completed succesfullly" as per software, but not recognized by system. This happens as if the media was not finalized. So far I've tried Nero, Instant Copy, TMPGEnc DVDAuthor, and Alcohol 120. I have had no success. Strangely I can burn cd's fine and DVDRWs fine. Any clues?????
