hmmm.... bad luck.
I tried with TV tuner removed... just ran mythbackend and mythfronted
(networked) but still the backend lost 95% memory within minutes.
I was watching a recorded program (HD).
I stopped backend but still didnt get the memory back.
free -m shows same.. same info in top.
ps aux --sort=vsz shows some other programs which are taking up around 600MB
out of my 2GB physical RAM. After myth server-client run, free memory is
only 180MB :(
Any luck ?
Should I compile mythtv from source ? Any compile time options ?
I have the utuntu packages right now... just did apt-get install mythtv
Looking for suggestions..
