[mythtv-users] [Solved] Unable to Watch Live TV or Record After Re-install

[Ian Barton]

I have fixed my problem, but thought I would post it here as I am sure 
someone else will manage to shoot themselves in the foot with the same gun:)

After a failed upgrade of my Master BE from Mythbuntu 8.10 to 9.04, I 
decided to do a re-install. My system is RAID1, both for boot and 
recordings.

I installed Mythbuntu by first installing Ubuntu from the Alternate CD 
and then doing an apt-get install mythbuntu-desktop. All my recordings 
were there and I could play them fine. However, I couldn't watch live TV 
or make any recordings. Since it had been a while since I had done a 
channel scan, I deleted all my capture cards, re-added them and did a 
full scan. However, still no live TV or ability to record.

Eventually the penny dropped while staring at the error in the logs:

The recordings directory had a different uid and gid from that in my 
original install, so was no longer owned by MythTV. A quick sudo chown 
-R mythtv.users /media/recordings fixed the problem.
