all my b/r movies are set to output at a 5.1 dts and other accecptable output channels (all have the same end result), as thats the premium sound format that my reciever accecpts. ive swapped out 6 different optic cables, ranging from the elcheapo radio shack to the 50.00 monster optic cable trying this on the same movie that glitched. my ps3 comes from a smoke free, kid free, pet free home and gets used maby 1x a week for movie purposes. its done this since day 1. i do NOT have this issue when playing thru hdmi directly to my plasma (panny tha just took a ****, thanks again panny), but then im negating the whole 5.1 dts sound format and listening to in in "crappy" stereo. ive double checked all the audio settings, less doing a master factory reset if thats even possible. im ready to drop another 150 on a good working b/r player just to avoid this problem. i used to keep a log of all the glitchey b/r movies, but i got pissed and thru it away after speaking with the sony rep. iirc, one movie was the last transformers movie. and on 90% of ALL movies during the begining portions (21st centry fox lion parts) the audio glitches, but thr movie is fine. odd for sure.
