Well, after looking through the mythtranscode source code I found that
if the source and target (for lack of better words?) codec are the
same, then it will just copy the video directly rather than

I've made a patch that will let you bypass this video copy so that
even if the source and target codec are the same, it will re-encode. 
Perhaps a better solution to this would be to only video copy if the
codec settings are the same as well..

Anyway, I will post a patch to the dev list if any of you are interested..
