The problem is when watching Residente Evil 1080p mkv with DTS. Is stuttering all the time. Tryed CoreAVC, PowerDvd with and without HWA, fddshow etc. Nothing works... It's not the movie because it runs well in another pc....

 

[Vampiro]

It's now fixed!!! It was a simple thing: bad setting in Ac3filter for DTS - was Padded Dts when it should be in Auto

 

[Vampiro]

No it's not fixed!!! Is doing it again in a random way. Also appens with other mkv movies with DTS sound! Please help

I think it's a problem regarding 1080p files... Don't know what to do...

Maybe your CPU cant handle them? An E2140 is pretty fast but those 1080p files are pretty demanding.

Also it looks like you are using on-board sound which sucks up more CPU cycles.
