updates for legacy content on aetv.com

Added some more handling for older video on aetv.com, I also commented out some current stuff that may be applicable again if they ever finish their site cleanup.

I had to turn off the default of setting H.264 video and AAC audio because this will not be applicable on older rtmp based flv content and there's not a way I've found yet to determine what type of content you're going to get based on URL, we only find out much later in the process (after pulling the SMIL).

Also not sure how best to handle the fact that the chosen resolutions may or may not be available ... not sure if/how this might affect some clients.  Advise welcome :)

This goes along with a new AETV channel (channel requires this in place to fully work).
