It was working fine about a month ago and now everytime i try to play a DVD, it either won't play, stop in the middle, stop at a certain scene while the rest of the movie is continuing, or freeze. I have no idea what I did, but I did a system file check and a Scandisk to make sure that all my files are good. It's currently set as a slave drive to my CD-ROM drive (I had it the other way around with the DVD as the master and the CD-ROM as the slave, but it still didn't work). I'm thinking that I did something to my computer, and I'm considering a format, but I would use that as a last resort. Does anyone have any suggestions as to what my problem is? Might it be a busted DVD drive? I have the Pioneer 106s. Thanks for any input.
