Hi,

I recently bought a 5.1 sound system and hooked it up to my Onkyo TXSR608 receiver through which I've connected my PC using HDMI.

I'm using MPC HC (KCP) to watch MKVs of blu rays I have (used Make MKV) and for a short while it was great. One movie used Dolby True HD and it worked great, showed up on the receiver display as True HD too. For movies that used DTS Master HD (showed up as HDMISTR on the receiver), I couldn't get it to work until I changed the audio renderer in MPC HC to my receiver at which point DTS MSTRHD showed up. Brilliant. Until I switched to a Dolby True HD movie and then back to the DTS Master HD movie.

Now, my Dolby True HD ones work fine but I don't get audio from DTS Master HD movies. I didn't change any settings, nothing. I just played one movie, then another and the audio just stopped on DTS movies.

Can anybody help?

Thanks,

Pindi
