My second backend is running on Ubuntu 64-bit currently (I'm going to install 32-bit SUSE alongside soon to check a few suspicions I've had about the problems I have). With Kyle's patch, I can record shows (although it seem to miss the vbi information??) and I can see running previews in the 'Watch Recordings' screen, but if I try to play a recording, the best I get is a few frames stuttering back and forth and much more likely just a black screen. stracing the process it seems to run into a FUTEX_WAIT and, well, wait.... forever... I'm a bit curious here then, why is the preview working but not the actual playback? Could it be the built-in motherboard soundcard? Is it an Ubuntu thing, a 64-bit or something else, like a driver issue? It seems like it is at least 64-bit related. More information when I have a 32-bit setup running on that machine, which I totally expect to work without issue. /Martin. _______________________________________________ mythtv-dev mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-dev
