fixed in latest master, thanks much

PVR via Tvheadend is still not working. Any information what might be wrong?
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?

Most likely yes. Unless they release a DTS codec (like the VC-1 and Mpeg2 codecs) this will likely continue to be an issue unless you use a passthrough device.

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.





I had no major problem with DTS on moderate overclock, but I've experienced a substantial improvement since I started using a monoprice HDMI switch with optical out that does DTS pass through to my pre-HDMI receiver. It cost as least as much as the Pi, but it's well worth it.
There are several things that might mitigate the dts stuttering issue. if using a network share go for NFS instead of SAMBA AKA windows shares, if using a usb drive try the native linux format EXT4 instead of NTFS

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?
My config:

turbo_force=0
arm_freq=900
core_freq=333
sdram_freq=450
over_voltage=2
initial_turbo=30

16GB mkv files with DTS play smooth without any stuttering. I dont have dts receiver.



I'm running:

turbo_force=0
arm_freq=1000
over_voltage=6

File system is nfs, using a MybookWorld network hard drive.

I'm not upping core or sdram at the mo as I don't want to risk corrupting the sd card.

Is it likely that core and sdram need to be bumped, or is it likely the network speed (all Ethernet) is the issue? 1080p ac3 files run fine, but DTS ones stutter and lose video/audio sync.
rbej, have you changed any of the openelec configs or settings to get things running smoothly? The specific video in question is 10gb in size, however I have other 10gb 1080p ac3 files which run ok.
And were i to try upping the clocks, what would be sensible settings for core and sdram to match the 1000mhz arm freq?
Try my config. Is 100% safe for SD Card. Maybe your Rpi is overclocked too much and slowing. Im not change nothing in audio/video options in Xbmc. Only change language, disable fanarts in background and no visualization. Im use my own compile OpenElec build r12502 with gui 1080p. Links in my signature.



my pi play's 1080p with dts without overclock using nfs
It's not the nas speed over the network that's the issue as my xbox360 plays the video fine. It looks like the audio is 5.1 WMAPro - could that be the issue?
