I extended libcmyth, but I also added some cutting to the 
beginning and end of the recordings manually to figure out 
how the recordedmarkup factored in to the skipping.

Since I knew that there was always at least a 5 second 
cut at the beginning and the end of a recording, that allowed 
me to figure out the offset.  It was a bit of a kludge and I 
wasn't happy with having to manually edit every show, but 
it worked pretty good.  Since the mvp is in the kid's area, 
I only worried about the pre- and post- cutting on their 

I did notice on longer recordings it didn't work as well, 
so sometimes I started to skip a bit late (or early) and 
resumed playing a little bit too early (or late).
