Cant Skip/FF through pre recorded tv

I've had Dish HD-DVR for about a week or two now and I was wondering how come I cannot skip commercials on pre recorded tv. Every time I press the skip button or the FF button, the "Live TV" thing pops up despite it being pre recorded. What's the problem?

What's the problem?

Let the smoke clear the room and try again:lol:

It evidently is still recording and you are caught up to realtime.
