Last year I bought a new computer Compaq with 512 mb and an 80 gig hd. I have been backing up movies for over a year now with no problems until recently. Last night I was backing up a movie and when it was over, I tried watching it and close to the end it would freeze up and not go any further. So I was thinking I had a bad disc out of the bunch, so I tried another disc and it worked with no problems.Tonight I tried backing up a movie, and where it shows the progress it never moved and it said it would take over 50 minutes to burn off. So I sat here and waited, with 10 minutes left to go the disc ejected and said that there was an error to try another disc. So I did just that, and the same thing happened. Is it possible my burner has died on me? I am using XP, with a TSSTcorpDVDRW DL Burner. Is the firmware out of date? Where do I go to update it? Which burners are good? Wal Mart has Sony and Lite on. Thanks in advance for any help.
