Code:

/opt/vc/lib/tvservice -a

And see if you get a line returned that includes AC3.

In general with 1080 resolution files, the Raspi chokes on the HD audio, not the video. If your display or receiver supports AC3, XBMC will pass that audio to the display untouched and all should be well. If not, XBMC may be trying to decode the HD and then mix it down to 2 channels. The Raspi's CPU cannot cope with this. For more details, see this post of mine (under another identity):

Other possibilities could be a weak or under-powered WiFi setup. Are you using a wired or wireless connection? Or is the file being read off USB?

Thanks for the reply. I can confirm its not the ac3 as I have other 1080 files with ac3 and dts that play perfectly. I am wondering if it is to do with the frame rate?
Playing these off hard drive connected directly to the pi - power supply is more than adequate 5V 2A
Thanks
