Thanks for taking a look at it, Mark.

This gives the user a better view of where they're cutting and speeds up 

For example, take the process of saving programs without commercials:  
This requires going into the editor, loading the comm-flag list and 
adjusting the cutpoints for errant flags.  When doing this I often flick 
back and forth to see the adjacent frames. It's kind of like having 
tunnel vision.  This lead to my original patch in #6322 - the basic 
functionality to display the current frame and the immediately adjacent 

Later I found the adjacent frames are useless when navigating through 
the recording. It's more useful to see the next few frames I'll seek to, 
then I can lower the seek amount to fine tune the cutpoint. Kind of like 
zoom in / zoom out.

Valid points. As always, you guys are welcome to do whatever you want 
with this. I'll help where I can if there's interest in getting it into
