OK, I misunderstood. :) I thought you meant replace it in the file so the
file was the same aspect as the source but with clean (ie, no static or
other junk) black bars. Guess I assumed too much.
This idea has been brought up before and could probably be implemented
fairly easily using code like the blank-frame commercial detection stuff.
Nobody has got around to doing it though. I might take a shot at it one
day, I notice more and more shows are showing letterboxed on 4:3 sets
(probably since they started out in HD and are showing analog for us lowly
people without HD yet). :) Not sure how much of the bitrate it saves in
the end though so maybe it's more of a convenience thing.
