Where "its own database" means, "if you run 2 completely separate MythTV
systems that have no knowledge of each other and no way to share data or
recordings or ..."

How to schedule stuff so that it only records on one backend?  Spend 30%
of your life in the EPG's and recording rules of the 2 completely
separate MythTV systems--the same way your cable company expects you to
do when you buy 2 DVR's.

But Kevin is right--it will work.  IMHO, though, it's not worth
it--especially since there's no technical reason not to upgrade to 0.22
(and new graphics cards are cheap).
