Which version do I have

[uncle hammy]

Is there a simple way to determine which version of mythtv I'm currently running?

[hyperair]

apt-cache policy mythtv

That should give an output something like...
mythtv:
Installed: (none)
Candidate: 0.20.2+fixes15513-0ubuntu4
Version table:
0.20.2+fixes15513-0ubuntu4 0
500 http://tw.archive.ubuntu.com hardy/multiverse Packages
In my case it shows Installed: (none), but in your case it'll show the version that you have installed.

Thank, worked a charm!
