Thank you for your input and understanding.

Just as a follow up to prove Jean-Yves' suggestion of NFS possibly being at fault here; I've just removed NFS from the mix, so my live TV recordings are being written to my local HDD at the default of /var/lib/mythtv/livetv/ and my NFS share from my FileServer1 is NOT mounted on the MythTV backend server.
However, my /var/lib/mythtv/livetv/ directory still looks like this after viewing live TV as a test:
joe at MythTVServer1:~$ ls -lth /var/lib/mythtv/livetv/
total 66M
-rw-r--r-- 1 mythtv mythtv 65M 2012-03-18 12:50 1003_20120318124747.mpg
-rw-rw-rw- 1 mythtv mythtv 12K 2012-03-18 12:49 1003_20120318124747.mpg.-1.100x75.png
-rw-rw-rw- 1 mythtv mythtv 90K 2012-03-18 12:49 1003_20120318124747.mpg.png
-rw-r--r-- 1 mythtv mythtv 0 2012-03-18 12:47 1003_20120318124746.mpg
And the database:

I have also upgraded to the latest 0.25 MythBuntu release this morning, just in case this fixed anything, so I'm now running:
joe at MythTVServer1:~$ mythbackend --version
Please attach all output as a file in bug reports.
MythTV Version : v0.25-beta-181-g43b55c9
MythTV Branch : master

This bug does seem to describe exactly what we're seeing, so I guess there's little more I can do about it, until it's fixed: http://code.mythtv.org/trac/ticket/10443
If there's any info I've missed out (unintentionally), please let me know and I'll get it.
Thanks,
Joe
