Having just bought a new Dell Dimension 8400, I decided to try the free trial version of Power DVD 6.0. I've used Power DVD 4 for years and figured the new 6.0 would be a nice upgrade. The computer came with version 5.3, which seemed to be stripped down and had some glitches that required a patch. Anyway, after I installed 6.0, I lost all sound when playing DVDs. Even if I use Windows Media player, no sound. All other sounds, including CD playback, are fine. I uninstalled 6.0 and put back 5.3, and the sound came back. My sound card is the Soundblaster Live 24-bit. At this point I'll probably just reinstall my old 4.0 version. Anyone having any issues with Power DVD 6.0 or are there other programs you recommend?
