It has been mentioned a few days back in another thread. You may have done much 
better, and saved a few questions over bandwidth, if you had done something 
similar with Myth that you did with the mpeg4 conversions. Namely, twelve 1U 
boxes, 1 tuner (ok, Nova-T) per box, with it's own disk, each being a slave Myth 
backend. No contentions there you can't figure out easy.

You just don't need that kind of brute power in backends, particularly if you 
are receiving mpeg-2 streams to start with. Putting each backend in it's own box 
with it's own disk means each can read/write without interference from any other 

Now the master backend, that's trying to schedule/control that lot, *thats* 
where you are going to need some beef.

PS I assume, since you are effectively rebroadcasting stuff over the net, that 
you have the appropriate permissions from the copyright owners?
