[mythtv-users] Are there any docs that describe the split between mythfrontend and mythbackend?

I believe the answer is yes. However, the disk that fills up
may not have the oldest files so it's a bit unjust.

And I use local disks to reduce network traffic and latency and
I don't want to spoil recordings if there are network interuptions.

The easiest way to calculate throughput is that 1MB/sec is 3600MB or
3.6GB/hr. My Default profile recordings are 1.7GB/hr so ~1/2MB/sec.
7GB/hr HDTV would be ~2MB/sec. 100Mb can carry on the order of 10MB.
