I've read quite about quite a few people having DTS stuttering issues in MP here on the forums but I haven't seen my exact situation solved yet...

Note that I am using HDMI directly to my TV speakers, no receiver or audio device capable of decoding DTS audio. So I don't want SPDIF passthru, I need a codec to decode it for me!

I have the Acer Aspire Revo (LE, the 1GB model which I upgraded to 2). I was experiencing blippy/stuttery audio for all "DTS In Container" MKV's regardless of how I played them (in MP or not). Then I tried diagnosing it using ZoomPlayer, as it gives very fine-grained control over codecs. When I removed ffdshow as the DTS codec, and switched to AC3Filter, the files sounded fine. However, I don't know how to do the equivalent in MP. There, the only option is for "MPEG/AC3 Audio decoder" - does this control DTS decoding too? If so, setting it to "AC3Filter" doesn't fix my problem anyway.

I have tried going into the ffdshow audio configuration and disabling it for DTS, but it seems to have no effect.

FWIW, I know that I could have MP launch Zoomplayer it will be fine, but then I'll have a bunch of issues with the remote, which ZP doesn't support natively like MP does.

Try and set AC3Filter as your audio renderer. Then in AC3Filter you can choose what to decode to (stereo, 2.1, 4.0 etc). Run MediaPortal in windowed mode while you play around.

Well, I didn't have the option for the AC3Filter under audio renderer, but you did give me the idea I needed: before, I had it set explicitly to the "Nvidia High Definition Audio" renderer, whereas by changing it to Default DirectSound (which is probably the default), it seems to work fine.

Stupid problem, easy solution. Thanks!
