I'm wondering if there is any way to create a custom device/app profile? I've seen a lot of posts regarding profiles and I've experienced a lot of confusion myself regarding which profile to use on tablet like devices which can have a lot of different apps that support different codecs. Unless there is an explicit profile for the app you are going to use, it seems kind of hit or miss. Sometimes I pick a profile and it transcodes things that don't require it. Other times it doesn't transcode things that need it. If there was some simple way to just check off the set of formats a given device/app combo supported then I could get exactly what I want.

To be specific, I purchased Mezzmo because of it's support of wtv files. However, I can't seem to find a profile (on either iPad or Kindle Fire) that will transcode wtv, but let everything else pass through which is what I really want. The profiles are great if you get a match, but otherwise they just complicate matters.
