Hi. Just in the last month I have been having problems playing BLu-Rays (m2ts files)from the hard drive. First it was VLC (even I re-install it) .The sound was o.k. but it kept crushing and Power DVD 8.o was mute. Today the problem reverse. The sound with Power is fine but it's VLC that went mute for the first time. I have wind 8, 3 gygas RAM memory and Ati Radeon 4300/4500 series. As I said the problem started just a month ago. Playing normal DVDs is o.k. Thanks for any suggestion.
