Heres the deal, I have burned over 105 dvd movies. I have used various types of software on all of them. I have recently started a log of what movies I ripped and repacked with what software to try and narrow the problem down. When playing a dvd which i have burned to dvd-r it plays Perfect without any problems at all. Then a month or so later when watching the same disk again, on the same exact standalone it slowly progressively starts having huge glitches throughout the move. It seems to get worse and worse the longer i watch it. I eject the disk, wipe it down, (although it is completly spotless) and replay it, then it plays good in the spots that it was messing up in earlier, and screws up in places that it wasnt earlier. I dont understand. I have watched some of these movies 4 or 5 times then suddenly it starts messing up like this! I even went out a bought a brand new dvd player thinking that that was the problem, and it wasnt, same exact thing. I have cleaned my dvd player and all to no avail. Anyone ever have this happen????????
