You see it good, while watching a news channel with this scrolling texts. I changed nothing else, only updated mythtv to 0.20 rev 11281. The mythtv playback settings, the nvidia driver settings are all the same. The studder can be stopped, if live tv is paused for a few seconds. In my frontend.log, there are the following messages again and again, that could have something to do with that studder: * NVP: Waiting for prebuffer.. 0 AAAAAAAAAAaAALAAAuAAAAAAAAAAAAA[[BR]] * WriteAudio: buffer underrun[[BR]] * AO: dropping back audio_buffer_unused[[BR]] I attach the complete frontend.log. Some system info: * Mythtv: 0.20 rev 11281. Playback settings: OpenGL Sync=on, Deint: Bob, UseVideoAsTimebase=on, big audio buffer=on, decoder=Default[[BR]] * OS: Gentoo Linux (the whole system 64bit compiled)[[BR]] * Processor: AMD Athlon 64 3500[[BR]] * Ram: 1GB Kingston HyperX[[BR]] * Video source: 2x DVB-S (Hauppauge Nova-S plus)[[BR]] * Graphic card: Nvidia GF 6600.
