Background: Just upgraded to HD. Had HR34 installed which was ordered with the CCK. Other DVR was an HR22. Installer could never get the HR34 to connect to my wireless router with the CCK so he removed the CCK from the HR34 and installed a new coax line into the room with my router and installed the black broadband deca. Both receivers immediately connected to the network but MRV was not enabled for my account. I phoned Direct and they insisted that the HR22 would not work with MRV so they shipped me a replacement HR24. I installed the HR24 but it refuses to the see the network and MRV does not work. I have done the following all to no avail. 1. Reset both receivers and used Setup to go back and set Share Playlists. 2. Reset the broadband deca and the router. 3. Reset the HR24 again 4. Chose Restore Defaults in Network setup. Still no luck. If I look in the Info screen it shows that the HR24 has been assigned an IP address. But down where it says Network there is an error about no ethernet (9). There was also a message on one of the screens about unplug ethernet and reboot receiver to set coax network. Still no luck. The installer asked me to phone him before calling Direct but I really don't have much confidence in the installer and his knowledge of the networking side of things. Any tips or advice? I had been thinking of getting a new Wireless N router anyway so would it best best to do that and request the CCK back? I am extremely frustrated at this point it trying to get all this to work. Apps still never worked.
