I am burning DVDs with DVDA2 and Ulead software, using a Pioneer A06. Over the last few weeks the new DVDs that I burn won't play on most laptop computers (new and older), but they play great on home DVD players, and on the computer that burned them. Everything used to play great on my Sony laptop and now none of the new DVDs work, but the ones from a month ago still play on it. I don't think I changed anything... Have tried burning them at 6000kbps and 8000kbps with no success. Have used Verbatim, Maxell and Fuji media with same results.

Anyone else find that issue? Anything I should be checking?
