Odd behavior with video/adio on older Pioneer PDP display

[osx-addict]

Ok.. So I tried our older PDP display (a 6-8 year old Pioneer plasma) with a newly installed Nvidia GT430 (with latest drivers) connected via HDMI.. The behavior of the video is super odd -- interestingly enough it was more or less the same way with the onboard Intel graphics HDMI output as well..

The symptoms are a very spastic video output in live TV -- frame rates vary from 60+FPS to usually more like about 3.7fps per the XBMC debugging features -- much like a roller coaster -- very slow -- then super fast like its doing a catch-up and then slow again.. While this is going on, CPU never goes beyond 10-20% tops -- no network to speak of here as both NPVR + XBMC are on the same machine -- no outside network aside from the content that NPVR is getting from the HDHomeRuns (1 channel over gigabit)

I'm attaching the XBMC logs in the off chance it might have some clues.. I did try using NPVR directly and after fiddling a little I get video that looks great (w/o issues) and audio that is OK as well..

If it matters, when viewing live TV from within XBMC, the mouse is super jumpy -- very hard to control and there is no audio..

The log attachment was not very successful.

Damn! It was late and somehow I guess I forgot.. Luckily I've still got the logs but I can't post them until tonight.. :eek:

By the way.. I was able to fix this issue.. It was all caused by the XBMC audio settings.. Once I set the XBMC output device to point to the windows driver for audio output (instead of some GUID'y looking item) AND disabled features my TV is incapable of directly handling (Dolby, DTS,etc) then the audio kicked in fine AND the stuttering video stopped and the typical video frame rates are about 59fps on average.. There are still occasional buffering issues that I don't see with NPVR directly but it's close to usable -- just not sure it's quite ready for prime-time.. For now I may just stick with vanilla NPVR until the XBMC front-end+plugin matures a bit more...
