Sorry if I wasn't clear enough -- I'll try to be more precise here. When I use an smp-enabled kernel, I can use kaffeine, mplayer, or mythtv and they all receive and record just fine for 15-30 minutes. After that the picture looks like the reception is terrible -- mostly green, sometimes with pieces of image around the edges and a few small squares of non-green (maybe signal, maybe noise, hard to tell) through the middle. The audio is similarly messed up, and the EPG doesn't seem to download correctly either. The changeover is sudden, but doesn't seem to happen after a fixed amount of time -- it's usually about 15-30 minutes. If I record programs in this state the recording looks exactly the same as the above description. If I play old files everything is fine, it is only receiving that has problems. Restarting the X server has no effect. Switching to another player has no effect. The light on the usb stick stays solid green, ie receiving the signal fine. It's not flashing as it does when reception is bad. Scanning for channels works partially: it picks up one frequency with 4 channels, but none of the other frequencies that it found when in a working state. It can still tune to the previously set channels, even though it can't detect them, although of course the reception is terrible. Unplugging the device, unloading the module, replugging, and reloading has no effect. Killing the X server and restarting has no effect -- after both those I still have exactly the same reception issue I described above. I took a shot of the contents of the movie via xine -- you can get it from http://steelgarden.com/badreception.png The shot was taken from a saved file that I replayed after rebooting with an non-smp kernel. I have also put my kernel .config file up at http://steelgarden.com/.config in case there's something relevant in there. Could it be a problem that I compiled the kernel with the dvb drivers as module, and then replaced the .ko files? Should I recompile with no hint of dvb in the kernel itself? I hope this is specific enough. If there's any other information I can provide please tell me.
