Hi,
I have a server containing the DVB cards, and a separate frontend machine using VDR via xine-network. In the frontend machine I have AMD sempron 3400+, NVidia FX5200, 512MB RAM. I'm using the tv-out (via S-video) from the Nvidia card, and I'm using xv for video output Greedy2Frame/GreedyH deinterlacer. My frontend machine also boots up through network and has root file system behind NFS on the server..
I have a very persistent problem with my system that I would hope someone could give some hints.. The video stutters occasionally, especially with high motion video e.g. icehockey and football. With these kind of content the video is not even near "smooth", it kind of stops and jumps every couple of seconds or even more frequently. But on the other hand with most of time with some "normal" content the problems are not so visible and disturbing. I think it is not about cpu power at least, the whole system load seems to be around 80% when watching.
Regards and thanks in advance..

Have you tried 50 Hz display mode? I got improvement with moving content when changing from 60 Hz VGA LCD panel native resolution to 50 Hz 720p HDMI connection. I don't watch much sports but the horizontally scroling news items and vertical text scrolls are now smooth. I use GreedyH and Xv. Have you tried XvMC? It gives for me very smooth video but unfornately it is not stable enough for every day family usage.

Hi, Thanks for the tip. I checked and happened to be using 50Hz already. But anyway it think I found the root cause of the problems. I had quite high CPU load (~80-85%), which was a bit odd considering the cpu I have (AMD 3400+). I turned out that my xorg.conf contained a small mistake; NvAGP was set to "1" although I had AGPGART loaded. Therefore AGP seemed to be disabled totally. I changed NvAGP to "3" and load dropped to approx. 30% and for now the video playback problems are history :)
XvMC doesn't work for me either, it's a bit unstable for some reason. At least it causes Xine crashes in channel changes etc.
regards, Mika
