I use one with a dual USB tuner and two virtual tuners per tuner ie  
four in all.

I ran tests for a few hours with various recording/watching combos.  I  
posted the power results on the list a while back.

It works fine for me, and I sometimes see 3 recordings at once whilst  
watching something else.  CPU usage peaks around 40% in these  
schenarios so well within the r3610 dual core.  I use mine as a  
combined fe/be.

One thing that is important is to have more than one disk to avoid  
canning a single disk.  I use the os disk with mysql and an esata for  
recordings.  I noticed issues in early testing without the esata where  
iowait would creap up and cause prebuffering pauses on the frontend.   
That would not be a problem for a be.

Can see a problem with your plan bar finding enough to record that much.

Where are you getting a Linux only r3610?  I can not seem to find any.
