I have been using Sony DVD+R solely for several HUNDRED backups. I do not usually watch the disk afterward. When I do I have sometimes notice a glitch. Now the problem seems VERY bad - I would say every disk or every other disk completely freezes about 10 minutes toward the end of the movie. I don't know if it's a bad spool of DVD's or what! I use Any DVD and Shrink and have turned my burn speed as far down as possible in the Any DVD menu. I don't have a clue what the problem IS. I tried another type of blank last night and it didn't reproduce the glitch. But I don't know if this means anything as the problem is inconsistent... Could it just be my burner - or what?? I still have a lot of these Sony DVD+R blanks unopened and I had planned on keeping the media all the same so it would be uniform. I buy my stuff at Wal Mart. Any idea what is the best quality brand I can get there??? Help! Thanks!
