When trying to play Cd's, movies, etc., my windvd10 pro freezes up and Microsoft detects an unknown error. I tried a different software and it gets the same error. I have an LG drive model CH10LS20. I have a HIS 4670HD hdmi video card that works fine. I have an asus zonar sound card. I have windows vista 32 bit. Dual core processor, 4 gig ram. The computer reads the drive and says what it is holding, it just won't play without the software locking up. I tried to reinstall the software and that didn't work.
