Fire ComcastTV - Bring up new MythTV backend

There have been some buffering issues with the current MythTV backend (AMD Athlon, 1.2 GHz, 750 MB).  A combination of memory and processor limits is the likely issue.  I'd finished building a P4 3GHz 1.5MB machine (tiber - I like the name particularly since tiber is liquid cooled) a couple of days ago so went ahead and installed MythTV backend and frontend and configuring to make the recordings.  Hopefully that will resolve the issues.

I decommissioned Amazon and moved its recordings to the 1TB drive using MythLink (http://www.mythtv.org/wiki/Mythlink.pl).

I added /usr/share/doc/mythtv-backend/contrib/user_jobs to PATH in /etc/environment per https://help.ubuntu.com/community/EnvironmentVariables (stumbled on the fact that /etc/environment holds name value pairs and is NOT a sh script).

I added

mythlink.pl --link /var/lib/mythtv/pretty --chanid %CHANID% --starttime %STARTTIME%  --format '%T-%oY%om%od-%S'

as a user job on RecordingStart so that going forward there will be links if they are needed and the recordings can be moved with reasonable names using cp.
