For which frame of the video?  Note that every frame in a recording 
could have a different resolution.

OK, in the real world, you won't see that, but resolution can change 
from one part of the recording to the next--i.e. from the show to a 
commercial and again to the next commercial (and I'm not even talking 
commercial breaks, here).  Note, though, that interlacing can actually 
change from frame to frame in real-world video--I'm assuming you're also 
interested in whether it's 1080i60 or 1080p30 or 1080p24 or ...

So, you're probably thinking, "Well, obviously I want information for 
the frame currently displayed on screen."  While it could be done, how 
helpful will it be if people don't realize that the instantaneous 
reading may not be indicative of the actual recording's resolution.

Regardless, there will be code in the future to scan a recording for 
resolution and other information and put a "best guess" of that info 
into the database (probably done at the same time as seektable building 
or possibly commercial flagging).  This, IMHO, is far more valuable than 
any instantaneous reading as it is most likely the info the user wants 
to know.
