Recently a number of Whole House DVR issues have developed in my system. I cannot watch programs recorded on one DVR any any other box without picture breakup taking place. This does not occur on the box the program is recorded on. Furthermore it does not take place on recording between channels 503 and 529. It is also not possible to fast forward a program recorded on another box. The program returns to the orignal spot. You can however forward by time skipping. Verizon Tech's have been to my house and have not fixed the problem. I am going to leave Verizon if this cannot be fixed as this was a major reason for switching providers. Any help would be appreciated.
