I am having some issues with playing DVD's on my PC. The PC is an HP Pavilion a520n. The DVD player is listed in the Device Manager as an HP DVD Writer 400c (came preinstalled in the PC). The video will play without any problems up until around 2:00 minutes in, and then will freeze. I can click the close button in the upper right corner of the screen and the player will close immediately. No error window pops up. I can even restart the video without any after effects. The video will again play, reach the same point in the video and freeze again. There doesn't apppear to be a memory problem as I can still perform other functions while the video is frozen. Playing video from the hard drive does not have the same freezing effect.
Some background info: I had a bad virus infestation a while back and after the cleanup, was when i first noticed this problem. Here are the links to the other topics pertaining to the virus clean-up. I don't know if they could possibly be of some help or not.http://www.bleepingcomputer.com/forums/t/114769/infected-with-virtumonde-and-vundo/
