Just a small question, does someone has problems with analog or maybe even with digital tuner cards the problem that when you're switching from one channel to antoher that the mythtv-backend crashes or even dies? So what i did to test something and maybe someone has an better idea then me, i just killed ( just for testing purposes ) the mythtv-backend proccess, and just in my terminal connected to my laptop ( to see whats happening ) spawned mythbackend ( so not mythtv-backend --> its only a wrapper and ads some logging to /var/log/mythtv/mythbackend.log and a pid number to kill it in my case ) and just what i thought and i really don't why but it rapidly speeds up mythtv and for sure switching channels with my hauppage pvr-500, and the most important thing off all -----> i switched back and forth with my channels for nearly then minutes and it didn't crashed a single time.
Hope that someone also found this and can tell us more about it ( maybe some scripting )
Happy to share stuff
iirc that race condition is fixed in the newest mythtv patches but they are not yet included in the beta.
