But we've since determined that's not doing what he wants (as neither 
Raymond nor I could tell what Brian's "one liner" was doing).  Instead, 
he wants something like Raymond's simplified version of the code (that 
you've trimmed) that Raymond provided as a "what you want, rather than 
what you're doing"--basically like the script in 
http://www.gossamer-threads.com/lists/mythtv/dev/519225#519225 .

Well, that's one purpose of an abstraction layer--and, yeah, none of the 
bindings provide that--but another is to provide a single code base that 
can be updated after changes to MythTV, rather than forcing every single 
script author to update every single script after changes to MythTV.  
This will become a much more visible benefit, before long, when I 
completely change the schema on everyone.  :)
