Nero 7 (Nero Showtime) Black Screen

I upgraded to Nero 7 (Demo B version) and have had no luck with Nero Showtime. When I first configured it, the DVD (on the HD) movie played perfectly. However, about half way through the first chapter, the screen went BLACK. Sound stayed perfect, just no picture.

I have tried just about everything I can think of to get the video back, but no luck. No matter what the source is, I have sound but just a black screen where the video should be. All of the menus work fine, all of the on screen configuration (drop down) work perfectly. No Video on Screen!

I also have Cyberlink's DVD Player 5, and it works perfectly. Great picture and great sound. No problems what so ever. (I installed DVD Player 5 AFTER Nero screwed up, just to test the systems ability to display the video.)

I have un-installed and re-installed the entire Nero 7 setup about 5 times now, and it stays the same. Showtime will NOT display the video portion of anything (any format) just plays the audio.

Suggestions welcome!
