Some still play fine in a player. Some of the really bad ones, like above, I couldn't even create an ISO file from. It was totally unreadable for that purpose. They do seem to be ok in the burner itself, but I haven't tried it all the way though. They also seem ok on my standalone dvd recorder. I'm sure my dvd player (sony) is being finnecky, but obviously from that scan the disc has problems.
As I mentioned though, new burns are ok and play fine. Just like before. Then they seem to go bad. I will scan a new burn and post it. It will have just been done.
The only other thing I can think of is firmware. Maybe something was screwed up in the write strategies. I just upgrading the other night. It's a 1673S@1693S KC48.
If a scan looks good after a burn, what else could I do to make sure it's not the burner itself? And again, some discs burned a while ago are still ok.
