I have a Toshiba Satellite laptop (I have to get the specs and exact model number later, I'm posting this from work because I have no internet connection at home) which I mainly use for playing DVDs and games. Up until about a month ago, it would play all of my DVDs just fine; I'd insert the disc, I'd hear the whine of the drive spinning, then two beep-like noises, then the WMPlayer would start playing the DVD. Then for a few of them, it would start whirring, , and make some other noises, then stop whirring, then start again like it's trying to read the disc again, and eventually it would just stop trying. I bought a DVD lens cleaning disc and have used that many times, but it doesn't seem to help much. Strangely, it doesn't seem to be caused by excessive scratching or smudging of the DVDs; I've put in brand-new DVDs straight from the packaging that won't play, but then I'll put in another DVD that has some scratches or smudges on it and it'll play fine every time. Any idea what might be going on? Again, I apologize for the incomplete info: I'll post that when I can. Thanks in advance for any advice!
