[mythtv] Play and honor CUT list immediatly from start

[Endaf Jonds]

I've been playing with the editing and cut-list features.  I can load up 
a recording that has been commercial flagged properly, no problem.  It 
skips the commercials very close to 100% without error (I'm very happy 
with it's accuracy!)

However, when looking at the edit bar at the bottom of the screen (after 
I have pressed the "e" key), it would appear the beginning is being 
flagged as a commercial (and this is totally correct is I start my 
recording's 30 seconds early).

It would appear that myth ignores the first "CUT" and plays immediately 
from the beginning of the video despite it being marked as "CUT".  
Shouldn't it start at the first available green section (non-cut section)?

But, feature, or oversight?  Would be nice to have the first bit skipped.
