My CPU is an dual core E05350 an does not exceed 50% CPU, much lesser when I use vdpau instead of XV, so CPU power is not the issue here. For ARD 1 HD and ZDF HD, video is suttering although CPU utilisation does not exceed 50% with XV. Same suttering problems when I used vdpau ( nvidia 8400gs ). Tried different deinterlacers and renderers but the problem persists ( little or no effects ) I was able to watch the recorded ZDF HD and ARD HD transmissions without any suttering at all using an external VLC player.. so this points to a problem with the internal player of Myth. Tried to play the recordings with an external mplayer player but it failed, the video didn' even start. Finally, tried with xine and it worked partially ( audio was terrible cracking an suttering ). I will post the mythtv log and possibly also the mplayer log. " defect closed minor 0.23 MythTV - Video Playback head medium fixed upstream ffmpeg 1
