I just installed this burner yesterday, So far I've burned 2 data DVD-R's of avi videos. On BOTH discs the VERY last video acts like it wasnt burned completly. It's the only file whose thumbnail doesnt display in explorer, and the only one that doesn't play. This is really ticking me off. I can't believe that my first burns with my first dvd burner have to go so wrong. Does anyone else know of this problem? Is it the burner, firmware, or perhaps the media I'm using? I have 2003 firmware, and am using Imation DVD-R's. If anyone else has tried this combination and/or can just give an opinion it'd really be appreciated.
