Moving to myth-dev for discussion.

I agree that the shift between screen modes is messy and can cause  
problems, but it has always been that way.

My problems with the length calculation and commercial skip missing  
only started somewhere in the middle of October.  Length for a 59-60  
minute recording is generally reported as 56 minutes in the OSD.   
This only happens on my HD-3000.  Recordings made with my PVR500  
report the correct length and seek correctly.
