Hi, I have finally managed to get everything working. However, every time I watch live tv I get those rather annoying 'prebuffering pause' messages. They occur every minute (approx it varies 20secs-2mins) and are accompanied by an AV pause. Playback in-between is smooth. I have tried the following: Setting audio device to ALSA:default and mixer to default Compiling latest ALSA CVS Swapping the on-board sound for an external SB MP3+ USB Turning on/off aggressive SC buffering and Use internal volume controls Turning on/off deinterlacing, realtime priority threads, XV picture controls Switching unused devices off in BIOS Switching ACPI on/off in BIOS Changing card priorities with setpci (for sound/gfx/tv cards) Compiling 2.6.11.4 kernel Compiling Myth CVS In addition: XV is working as I get the 'using XV port' message on the front end. CPU usage is 22% watching tv. Memory usage starts with 250MB free and works its way down to 2-5MB free. Xine DVD playback is fine and smooth. I have also scoured the mythtv-users lists... None of which has made any improvement! The only thing that has made a difference is taking out both tuners and putting in an old bttv card (I still get the pauses but they are more random and less frequent). Suggestions welcomed as I am unsure where to look! Hardware/Knoppmyth version info in sig. Cheers, Graham |
