Thanks for your support Steve.

Others have taken on my current patches and included them in their own
builds of MythTV. I believe that handbrake also uses a version of my patch
and XBMC is in the works as well.

That's what has prompted me to try to get them rolled in to ffmpeg. Of
course I want to do it the right way though. So if a decoder is wrong and
a bit stream filter is right, then bit stream filter, here we come :-)
