Can you try and post some hard information on your problem.  Please integrate my timing lines from my previous message in this thread.  This shows exactly which lines of the channel change are causing the slow down.  Without this you are just guessing as to what is happening.

You also missed off a lot of other interesting information.  For example what version of myth are you running?  latest CVS or version 0.12?  Also, do you see the harddrive thrashing during these 10-15 seconds?
