That's a known issue, and an unavoidable race condition.  The script 
tells the backend to delete those recordings, and the backend threads it 
off and takes its time doing so.  By the time the script rescans and 
returns to the user, only a handful of those files have been deleted.  I 
could set up a thread in the bindings to listen for the relevant events 
indicating deletion, but for now, I just handle the error and dump the 
user back to the list.

This is a known issue in trunk, where the the connection classes were 
rewritten to use two independent connections for commands and events, to 
more correctly duplicate the behavior of the frontend.  Certain things 
like the automatic reconnection have not yet been fixed, although why 
the bindings think they need to reconnect, I don't know.

Python 2.x and Python 3.x are two completely independent languages and 
can co-exist on a single system without issue.  There shouldn't be a 
need to uninstall 3.2 to install 2.7.  IMO, it was a very poor choice 
for Arch to make the Python 3.x binary the primary 'python' binary, 
since as you're discovering, it breaks all sorts of things all over.  
When you compile MythTV, configure takes a '--python=' argument, which 
sets what binary you want to use for the bindings and any internally 
installed scripts.  External ones like mythvidexport.py will have to be 
set manually.
