Got a problem. My DVD-Rom won't play some movies that have been released in the past few months. This is a new external DVD-Rom drive (I was having the same problems with the internal one - besides, I needed a new one because the internal one won't write to disks anymore...). I have disabled the old DVD-Rom, restarted the comp, tried to play the movies that weren't playing and no luck. Upgraded Windows Media Player, still no go. The disks are unscratched and will play on other people's DVD players. This doesn't happen with all the movies I've rented so far (the recent ones that have come out in the past few months). I have returned them for replacements only to have the same problem. Been trying to find similiar topics of this nature but have had no luck. Let's see, more details... The drive keeps running trying to read the disk, but can't. The comp will start to slow down and on one occasion locked up my computer (I won't let it go for more than a minute or two and will eject the disk). Any advice?
