Unpredictable digital problems with movies?

Weird...might it be pirated DVD'S? - some pirated material from market/street sellers is very hard to tell from real thing (when looking at the package)?

Sounds like a DTS issue, or a layerchange, or rental DVD's... I would look at your DVD player not the processor as the problem. Try another player on those same pieces of media.

Shadorne: is definitely right.. buying movies on ebay/half is a nightmare...

No pirate or rented DVD movies here, it was playing in dolby digital EX not DTS, its funny you mention layer change as I almost added to my original post I thought maybe it happens at chapter change. I had this issue with a Samsung HD841 and had it replaced and same thing happened, then I had the Rotel serviced with a new unit being sent to me to solve my complaint. I was using a Sony player and had no issues, but now it is back with the Lexicon and I feel with having other players act this way it is in the Rotel where the problem is. All the same I cant figure out what it is.
