I'm new to XBMC (V12.2 Frodo) and am running the software on a WIN8.1 Haswell (Assassin-built) HTPC system connected to my Denon 4520.

I've successfully played MKV movies in XMBC but am having a peculiar problem with BluRay ISO files.

Strangely, the preview trailers in the BluRay ISO play perfectly ... no video or audio issues. Once the BluRay menu is up and the actual movie is started, the video begins to stutter and play very slowly -
like in slow motion. No audio is audible at this point.

I've checked my settings but can't seem to make this work. I've seen similar threads on this topic but the solutions don't work.

Any ideas on what's going on?

Thanks,
Herb...
