Unpredictable digital problems with movies?


When I am watching movies with my Rotel RSP1068 I sometimes get an unexpected digital glitch that is very loud and potentially damaging to speakers, it is hard to describe but it sounds like a "gargle" sound, has anyone ever had this problem? It comes out of nowhere and is unpredictable, I am wired to Lexicon RT10 with Cardas Hexlink. Thanks for any thoughts or help

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.
Well this is probably a stupid idea and who knows if it will help but I hooked up a Monarchy DIP just for the sake of trying it........so far no issues, if this helps I wont know why. The disc I was playing was "The Incredibles" and it has 2 discs in it and was purchased from SunCoast at the mall so I highly doubt it is a scab DVD, I bought "Second Hand lions" at a flea market a few years ago and learned my lesson about well packaged crap.
