That begins to make sense. My setup is essentially the same as yours,  
right down to the timezone (I'm in Cheyenne).

But, at the time of the DST change, I think I had perhaps one  
recording scheduled that was after the change. Being a paranoid type  
I intentionally tried to not schedule anything after the change until  
it happened.

I did have a couple of "glitches" with recordings that were happening  
at the exact time of the change, but that didn't surprise me and it  
is not the problem you're having.

I suppose you could delete all of your scheduled recordings and re- 
schedule them. DST has always been problematical for broadcasters,  
although normally the "extra hour" was more hassle than the "missing"  
one.

There should be a DST section in the WiKi, if I can accumulate enough  
info I'll be happy to write it up, so please post whatever your final  
answer turns out to be.
