I had 2 HR20-100 dvrs and 1 H20 receiver going into my deca install on Sunday. The H20 was swapped out for an H24 during the installation, as expected. The install was very tough, as the installer could not get any of the units to 'see' any of the others. In addition, one of the HR20 units would not light up the deca attached to it. Through equipment swaps we determined that the problem with the lights was emanating from the receiver, not a deca or the cabling. In any case, after much trial and error, I suggested we run a cable from the SWiM directly to my router, based on posts I had seen here. After making this deca connection and numerous box resets, all units could see each of the dvr playlists, even though the lights on one of the decas remained unlit. We were able to access and start watching recordings from each of the playlists on each box, so we called it a day and he left. Last night was the first time I actually tried to watch a show that was sitting on the other HR20-100. After a few minutes, I started getting continous audio dropouts that made it all but impossible to watch. This is the same problem I had when I was trying to use the beta version over ethernet. My hr20s are connected to my home network via Powerline adaptors. I had read various comments that Powerline was not sufficient for dvr sharing, so I gave up on the beta and decided to wait for the deca install. Unfortunately, as I said, I still have the same problem. I have read here that there must be a cable from the SWiM to the router for an HR20-100 to work. Does that mean that I could not have a successful deca install if I did not have a home network in place? If that is the case, do you know how D* would deal with the situation? They did not ask me if I had a router or network when I ordered the installation. Is there any way to make the current configuration work, short of hardwiring the dvrs to the router? That is not a viable solution. I am going to call D* shortly to let them know about the problem, but I would really like to hear your opinions and advice before I talk to them. Is this problem likely to be resolved by replacing the HR20-100 units? Do you think it may be caused by the one that won't light up the deca? Any input will be appreciated.
