Hi Jeff, I registed on AVS just for this because I am having the same problem. I posted this over at overclock.net and it sounds like it's a hardware issue
I have an LG blu-ray player (UH12LS28)
Crosshair IV Extreme Mobo
AMD 1100T 6 cores
Whenever I play blu-ray disc, sound/video would intermittently drop for a split second, occurs 2-3 times within a span of 5 minutes. This occurs throughout the entire movie, on ANY blu-ray.
It occurs with all my sound peripherals, including z5500 speakers, creative 2.1 speakers, headphones.
It occurs on any audio setting (stereo or DTS)
It occurs with my speaker plug AND optical output from the MOBO
It occurs with HDMI output from my 560 Ti
It occurs with both Arcsoft media player and powerdvd media player
It does NOT occur with DVDs
It does NOT occur with ripped movies (though I don't rip blu-ray)
It does NOT occur with any gaming (BF3, Batman Arkham City, etc)
It does NOT occur with music files
It does NOT occur with anything other than blu-ray playback
I have pinned it down to the blu-ray player itself. Anything else I can help differentiate?
I thought a sound card might fix it, but that wouldnt make any sense. It occurs with both the MOBO soundcard as well as the nvidia GPU via HDMI output.
I called LG and they were useless. I think I may get another blu-ray drive and push the current one to DVD/read only on my other computer
(BTW, I used to live in san jose, indy high class of '97 w00tw00t!)
