I have recently changed my cable provider to att uverse. I upgraded my remote to the harmony 890. The pvr provided by att is the motorolla vip 1216. All of my connected components work well with the 890 with the exception of att's pvr. Att's equipment works sometimes with the 890 but it is hit and miss. Has anyone else had this problem? If so, what is the fix. Any info would be much appreciated.

thanks
