Hi guys,

I've used PowerDVD 8 Ultra for the past couple of years with no problem. Just a couple of days ago, I did a reformat of my computer and also replaced the Lite-On DVD burner that had broken down on me.

After the reformat and after installing the new LG GH22NP20 super-multi drive, I discovered to my horror that I'm no longer able to experience smooth playback of my DVDs. Below is a detailed description of my problem.

1. Video/audio stutters/freezes significantly during DVD playback using PowerDVD 8 Ultra and also PowerDVD 9 Ultra (both updated, but never installed at the same time).
1. Playing DVD from hard drive (i.e. ripped to computer) is OK - silk-smooth playback
2. Using WMP11 to play the same DVD on the SAME LG DRIVE is NO PROBLEM!
3. In conclusion, the problem only surfaces when I use PowerDVD 8 or 9 to play DVDs in the new LG drive. But the same LG drive works flawlessly when playing the same dvds using WMP 11.

Obviously, my first thought was that the new LG drive is faulty. But why would it then perform flawlessly when I play DVDs in WMP11? Any help would be appreciated!
