Buffering of HD channels in XBMC only

[Fritters]

I searched for this problem and didn't find anything that seemed to match my problem...

I'm using XBMC 13.2 with NPVR 3.2.9.
TV Tuner: AVerMedia AVerTVHD Duet PCTV tuner (A188) A188-AF PCI-Express x1 Interface
GFX: RADEON 7700
CPU: AMD X4

Also, I run the audio/video via HDMI through a surround sound receiver before passing to the TV in case that's relevant.

When I'm watching through XBMC, all of the HD (1080) channels are constantly buffering (they buffer from 0 up to about 15%, then play for about 5 seconds before buffering again). The buffering takes several seconds as well. I've left it on a channel for several minutes and the problem doesn't seem to resolve itself and occurs on every 1080 channel that comes in. I've never seen buffering on the SD channels beyond when I first select a channel.

This issue occurs only in XBMC - all channels work wonderfully in the standalone NPVR client. I'm basically using all defaults in NPVR and XBMC using LAV for all of my audio and video encoding (I'm not very well educated on codecs, but they seem to work fine in the NPVR client).

Thanks for reading - any help is greatly appreciated.

Are you using wireless?

[Fritters]

Nope-everything is wired. NPVR and XBMC are all running on the same PC, though they are installed on different drives. XBMC is installed on my windows drive (a small ssd) and npvr is on a separate drive I use for programs.

I wish somebody would figure this out! It buffers so much that I get minutes behind in a football game. Doesn't matter which network; GigaBit wired, G wireless or N wireless.

ServerWMC works with no buffering over the network to KODI, even on G wireless, but for other reasons I would rather use NPVR.

Mine is 2 AverMedia M781 and 1 Hauppauge card on a Windows7 Ultimate machine serving an all Windows 7 Ultimate network + 1 Openelec RPI. It is not as active as it sounds, rarely more than one client is even connected at a time.

I've never seen this happening here.

If you disable timeshift mode in the addon settings, does it help?

[donbrew]

no.

I have read about it here and elsewhere. Seems that the threads always die before anyone comes up with anything. I have been trying since before Gotham came out hoping that XBMC upgrades and npvr upgrades would fix it. DL'd npvr 3.3.8 have not checked it out yet.

Did you try changing the deinterlacing method?

Just so you know he's not alone I have the same problem, live hd buffers and stutters but standard plays fine. I can watch any hd recording with no problem.

I'm new to Nextpvr but I'm also having the same problem. The HD channels look great but buffer. I messed around with the video preferences but nothing seemed to affect the problem.
