(See below for my logs and why I thing this is the problem)
So I have 2 questions for this list:
(1) Should I expect NFS to manage? Searching the internet does not turn
up many other people having problems. I have got file caching turned on

It should manage, but you need to tell us *way* more about your
setup.<br>

Personally, I would avoid this as the ssd will wear out <br>

For example I recorded Back Benches and at 16:17 the recording just stops.
The recording started at 22:29
The log said (mythbackend.log):
Jun 4 22:29:00 gently mythbackend[1425]: I Scheduler scheduler.cpp:2514

I assume it is writing to 1010_20140604222900
I get a few messages like:

Then the last mention of the file is:
