I am running mythtv on Ubuntu Feisty, using the package lirc-modules, which I says it is 0.8.1 + cvs20070310-0ubuntu2 + 2.6.20-16.31. I am using the basic homebrew serial receiver and transmitter directly off the COM port (no external power). My TV tuner is an AVerMedia A180, which uses the saa7134-dvb driver. Whenever I do an irsend command, my tv tuner (ATSC over the air video) loses data, which results in a momentarily corrupted picture and/or blips in the audio. This happens in both mythtv and mplayer. Receiving IR signals does not cause this to happen. Originally I thought that maybe it was just an interference thing, but it happens even if I unplug the COM port, therefore it is software related. I tried changing the IRQ and port of the COM port to see if it was IRQ related, and that made no difference. I tried running with a nice -19, but that made no difference. Is there some setting I'm missing in configuration to tell irsend to play more nicely? ____________________________________________________________________________________ Shape Yahoo! in your own image.
