Spoke too soon, here's the log output, where as when changing channels i
had a hang and then had to do a force restart of myth, now it seems to seg
fault out, this appears to be shown after running for 12 hours. i have
rebooted and can now watch tv again.
Let me know if you want me to do a debug build and trace it.
