Nope.  Best you could do is make a "macro" to send all the appropriate 

Daniel has been talking about the need to separate out aspect ratio 
overrides from zoom modes, at which point it would be easier to add 
support for "remembering" custom zooms, but he has a lot of more 
important tasks he's been working on instead.

It seems to me that often broadcasters do a poor job of centering and 
maintaining aspect ratio when inserting letterbox/pillarbox bars, but I 
haven't done any real testing (nor have I had access to their source 
material to allow proper testing).  So, I may be off my rocker (or my 
Myth box or my TV may be improperly configured, making it look like a 
problem in the video I receive from the broadcaster).
