In my shell script I use zenity to give me a selection box of which system to connect to.  When I launch the program it puts up a nice selection box so I can easily connect to whichever backend I want.  I also modified the desktop file for mythfrontend to point to my script.  Works real nice.

Same way he's handling differences between 0.27 and 0.28 
libraries/executables--he has 2 installs in different locations and he 
has 2 different databases.  The 2 different databases is why he needs to 
switch between the 2 different systems.  Whatever show he plans to watch 
is apparently in only one of the databases.

That said, Dennis, another option is to just stick with whichever 
version of MythTV you have running and use Video Library to play the 
other recording.  You can use mythlink.pl to create well-named links to 
the shows on the other system and then make those links (or a copy of 
the file--whichever is easiest with your network/storage layout) 
available to Video Library on the system you're using.  I'm pretty sure 
you can even do commercial detection on the Video Library videos.
