I'm not sure about the current version of that script (as I'm not using 
it), but there are some common things I see lacking in scripts in general.

Also, the ability to update channels in the database using the 
appropriate ids.  With DVB you scan for the channels and then have to 
update all of the xml tags.  Be nice if this was handled by the grabber 
(similar to the way the channels.conf importer works).

That would be nice.  I'm using MythTV for FTA digital only, but it'd be 
nice if the script could grab digital, analog (not all are transmitted 
in digital yet), cable and satelite program info at once (if all are 
available from the same source).

Good, except ABC2 and SBS News are two channels I record frequently.  
The guide I'm currently using supports them.  The big "missing" at the 
moment is a script that can indicate when programs are "simulcast" on 
the HD channels.

You'd still need to query the start and end times.  Unfortunately, the 
start and end times are frequently innacurate anyway.
