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

thanks for the reply. I called Lexicon, no upgrades.
again this isnt the players fault as I had same issue with my last player...so it has to be a Rotel issue, but they plead ignorance.
Sorry, I meant call Rotel.... but unfortuantely sometimes my EAD would drop but it was completely silent through the speakers.. it was my cable company switching between audio formats between each comericial on my Cox.. My Meridian does the same thing.. it's my Cox Cable box... The De-jitter box (Camelot Dragon 5.1) didn't help the drops but did clean up the sound.

Not sure what else to say.. try a cheap $29 dvd player.. I've read the Panasonics are the most compliant to read errors. I know it doesn't go over well....
My cable has done it also now that you mention it, I held the button in to re-boot it, Rotel claims no issue ever but I take that with a big glass of "yea right"
