There have been many threads about this subject but none of them seem to touch on this post I found on the XBMC forum
http://forum.xbmc.org/showthread.php?tid=141039&pid=1278121#pid1278121
I was asking if I could change codecs to aid in lowering zapping time in XBMC the responce was no but they can work on the codec (FFmpeg) to allow faster switching.
Now MediaPortal has support for LAV which is based on FFmpeg so can we maybe use these changes to benefit the MediaPortal community?

I'm still trying to find a way to speed-up the channel switches, but this probably requires patching ffmpeg.
We have been working on this: https://github.com/FFmpeg/FFmpeg/commit/...73f7b49702
Now we can detect pmt changes on the fly and can skip analyzing the stream for ts. You need to send pat/pmt changes in the stream.
