Pause, rewind, fast forward not working

I just replaced my XiD-P set top box due to a download error message I was getting, and now on the new box I no longer get the error message but it says pause, rewind and fast forward are not supported. Which is odd as it worked immediately after I set it up today but only for a few minutes. I've tried unplugging and no luck. Any suggestions?  I had this same issue on a box in a different room and replaced that box today as well and it now works.
