I attempted to use the search feature as I figured someone has encountered this problem already. But no luck. Anyway, I purchased Twister on blu ray today and the audio drop on the tru hd track drops constantly. I have never had this happen before and I own several blu ray discs. I have an Onkyo 905 with DSP update, Panasonic BD30 with latest firmware, and a DVDO Edge with latest firmware. This is extremely fustrating. I've tried everything but I can't figure it out. I'm thinking it may be the disc but I'm not sure. Any help would be greatly appreciated.
