I think there must be a problem in the VDPAU driver for the GT520. I use this card in my HTPC to view TV over satellite on Astra 19.2.
There is one channel i cannot watch, called "Servus TV HD", an austrian channel. Most of the times i just see green artifacts. I already tried with xine and XBMC. If i use ffmpeg CPU decoding, it is working, but not with VDPAU enabled.
Sometimes this channel works, but then if i switch to another channel and switch back to Servus TV, i get green artifacts again.
The problem exists since i bought this card (ASUS ENGT 520 silent). Other people also have this problem with this channel. Will this be fixed in the future?
Here are the codec details of a recording, maybe this will help.
