Glad (for lack of a better word) that I am not the only one having this issue.
I'll try disabling powerplay again. I am not running GPU-Z during playing.
I'm only testing with TMT, because it's the only one I have. Plus, once I finally figure this out (assuming I do) I want to use MyMovies w/ TMT.
Should I test it out with MPC-HC? Just open the m2ts file with it? If so I'll try it tomorrow.
Have you tried turning hardware acceleration on and off in TMT?
You should definitely try bitstreami playback with MPC-HC and ffdshow (outlined nicely here http://www.mediasmartserver.net/2010...7-htpc-part-i/
) just to make sure you're on the same page as everybody else and narrow the problem down. It sounds like your problem is most likely related to DXVA and Powerplay.
With my 5770 and onkyo 606, i found that when using MPC-HC's internal DXVA VC1 and AVC video decoders, playback was smooth and no audio stuttering or popping. when i playback without DXVA though (ffdshow video decoder), i get audio dropouts and choppy video.
In GPU-Z, i noticed that the GPU ran at 157/300 at idle and ramped up to 850/1200 during playback. I haven't even touched the Overdrive section in CCC yet. Instead, i used the AMD GPU Clock Tool and set it to 157/300. This immediately gave me perfect audio and much smoother non-DXVA video once i restarted the player.
For some reason, forcing higher clock frequencies did not fix the problem. only full-time 157/300 seems to work for me (maybe thats the only speed that disables Powerplay completely?). Since I use MadVR which siupposedly uses the GPU more, I'd like to be able to set the video card clock frequency higher and still have smooth video and no audio dropouts though!
