Hi JohnnyJboss:

Thanks for the response.

The reason I am not using the default storage location is that when I
installed Ubuntu on this box, I put the bulk of the storage at the
/home mount point. :(  As the system isn't really anywhere yet, I
don't think it would really be a big hassle to rebuild it with the
bulk of the disk space partitioned to the /var mount point.

Thanks for the link on how to "enable the automatic trunk builds".  As
a lot of this MythTV-Linux stuff is a bit mysterious, can you tell me
what exactly is the advantage of enabling this...repository I assume?
Is this to get the latest version of Mythbuntu with all the fixes?
