i have been on the phone about 10 times with directv and still no luck.the problem i'm having is with the dolby digital sound only.it cuts out every once and awile for a second.i have a samsung hd reciever hooked up through my stereo reciever.the odd thing is that this was happening when i had my tivo reciever hooked up.then it was only doing on showtime once and awile.now it continues to happen and also on the hd channels(more than the showtime channels).i went out and bought a new optical wire thinking it was that,still did it.they told me to try coax.went out bought one,still did it.cant be the directv reciever cause it happened with my old tivo reciever.tried running new rg6 cable from the splitter where its grounded,no luck.so now there saying its my stereo reciever,but it cant be. i watched 3 movies yesterday and didnt happen once!its driving me nuts!could it be the dish?there telling me no way,but theres really nothing else it could be.anyone else have this problem?
