I actually planned way ahead with vdr hanging. I stopped trying to make vdr 
so stable it never needs maintenance and included a key on my remote to 
run killall -KILL vdr with irexec :)  

I have to use it maybe two or three times a week. 

The hang appears to happen pretty much the same way every time.
When no one has been changing channels for a while (many many hours, never 
had it happen while I was actually watching something) cpu load drops to 0 
and it just starts throwing up stuff like this in the logs

vdr[24832]: buffer usage: 70% (tid=6029322)
vdr[24832]: buffer usage: 80% (tid=6029322)
vdr[24832]: buffer usage: 90% (tid=6029322)
vdr[24832]: buffer usage: 100% (tid=6029322)
vdr[24832]: ERROR: 1 ring buffer overflow (177 bytes dropped)
vdr[24832]: ERROR: 14383 ring buffer overflows (2704004 bytes dropped)
vdr[24832]: ERROR: 14766 ring buffer overflows (2776008 bytes dropped)
vdr[24832]: ERROR: 14682 ring buffer overflows (2760216 bytes dropped)

It'll keep doing this forever.  Sometimes it hangs so bad you have to kill 
it and sometimes simply switching channels makes it go again.

This is really the only type of crash/hang I get. The rest of the system is 
always perfectly fine no matter what vdr does.
