I've been burning DVD movies for a while, using a lot of different programs and media. Recently I have been having problems with playback. I have a nice, new Pioneer burner and have been using Taiyo Yuden DVD+R (8x), after switching from two other DVD+R formats. The problem I have is when playing back, my DVDs will start hanging-up after some time (ranges, but usually 10-30 mins into the movie). I can take the DVD out of that player, stick it in another player and it will go for another 10-15mins and start hanging up at another spot. Or I can turn off the DVD player and wait a while and start back up at the same spot on the same player with no problem until another 15 mins when it hangs at another area. I've tried them on a bunch of different players and it is consistent. Sometimes they may work, but more often than not they start hanging-up. It first starts with some "flickers" that get worse and then eventually the movie just hangs. Sometimes it may go way more than 10-15 mins and sometimes less. The DVD players range from two new standalone players (a Panasonic and another) to two laptop DVD players, to a portable Panasonic, to an older Sony standalone. Interestingly, the old Sony standalone seems to do the best, but is not immune to the problem. It doesn't seem to be a problem with a spot on the DVD, because like I said, I can turn off the player and back on and the same area that was messed up before will play perfectly. I always use DVD decrypter to burn the movies onto my hard drive (P4 1.5GHz, 512MB ram, Windows Xp SP2). Then I may use DVD shrink or not. Then burn with either Nero or Ulead (both produce problematic DVDs). So here are the things I could think of: maybe the DVD is heating up and having problems at that point. But, I allow the player plenty of breathing room. Or maybe it is the +R format? Or maybe I should not be burning at 4x-8x (maybe 1x?). I can't really figure it out. The only thing I haven't really tried yet is DVD -R's. Does ANYBODY have any ideas? Has anyone else had this problem? Oh, and if I forgot to mention it, I have tried two DVD writers ( I bought the Pioneer dual layer recently, I had a Pacific digital before). And the problem happens with both 4.7GB single layer disc and double layer. Please help!
