Hi Mike,

I've just upped my timeouts to 7000/10000 as you suggested. 

I tried watching live TV from one frontend. The 0B file was there for a few minutes (approx 3-5 mins), then disappeared, both from the list of files and from the list of recordings in MythWeb too. Changing channels did not cause a 0B file to be created. -- great...

I closed and re-opened MythFrontend, opened live TV, 0B was not created.

I opened live TV on another frontend, on a different channel. I'm 99% sure this was the point when the 0B file was created again. Unfortunately, this 0B file has not been deleted yet (after 25 minutes)

So, at this point:

ls -lth /mnt/mythtv/livetv/

So I changed the timeouts to 14000/20000 to see if that made any difference.

Opened live TV on once frontend, 0B file was created but not deleted, even after 10 minutes.

Here's my live TV directory now:

Also, FYI, I'm currently running:
