In short, yes, it's just a normal DVD installation (so follow the instructions for a DVD installation in the wiki).
I installed the latest snapshot (23165 at the time) and I have had nothing but a pleasant experience with it. I did change the etc/apt/preferences file as per posde's post (http://forum.linuxmce.org/index.php?topic=10309.0
) before I double clicked the LinuxMCE icon on the desktop, not sure whether this was necessary or not.
Let's put it this way - I didn't have any problems with mythTV installing, or getting the cards to work, so I have to assume that it was indeed necessary.
