1080p videos with DTS audio are still problematic too, stuttering even with a 1ghz Pi. Is this an issue which is likely to go unresolved until the RPi Foundation sort out hardware DTS decoding?

I play smooth EVERY mkv movie with DTS audio. No stuttering. Medium overclocking. 900mhz. Overvolted-2. Force Turbo 0. Initial Turbo 30. Im use NFS.

Same here.. Although I run at 1050/500/500 I found that 900/450/450 (even lower) and files of size 15GB 1080p with DTS sound over samba is no problem at all.. Try raise your core if you can.. How large are your files?
