I recently installed Mythbuntu 11.10. But the myth backend wasn't starting automatically. So added the below line to /etc/rc.local to start the mythtv-backend while booting.
However, I cannot get live tv without manually restarting the backend. As per the mythbackend.log the DVB device (/dev/dvb/adapter0/frontend0) isn't available at mythbackend startup (file not found).
start mythtv-backend start
(I use an af9035 DVB-T (USB) device and followed this post to install the driver. http://askubuntu.com/a/84611/48674)
Anyone have any ideas on how to fix the issue?
