Lately the DVD player on my laptop has been acting strangely. It will play a movie just fine for about 30-45 minutes and then out of nowhere it starts to get choppy like there is a scratch on the disc. It does this with every movie I've tried so far. It has always worked fine before up until a couple of weeks ago when it started doing this. Where should I start? Is the video card going out? It has 64mb integrated graphics if that matters. Could it be the DVD drive? Is it just overheating? I'm clueless so any help will be greatly appreciated.
