Slowly, but surely.
I am waiting to talk to janneg from MythTV as he is the maintainer of the 
patches to ffmpeg in myth. Once I have talked to him I will have a better 
idea of how I should proceed.

You can always download the patches from my site and build it yourself.

Bear in mind that there are problems with the interlaced channels i.e. lots of 
motion artifacts. The 720p channels look real nice. Also, there is a lag 
between the video and audio of 0.5 seconds. I need to figure out how to fix 
this as well.

Cheers,
Paul
