I have a a STB in another room connected via ethernet to the modem through a router (DLink DIR-601). The STB is only connected via ethernet and not via coax. Live TV works fine, no dropouts, no issues (had to turn multicast on in the router options or it was losing signal after about 15 seconds or so, but once I did that it was fine).
Now, the problem occurs when I try to watch recorded programs. It tells me "make sure this TV receiver and the DVR receiver are connected to the network". When I plug the DVR via the ethernet port into the network it completely overwhelms the network (TV signal is reduced to stuttering, internet becomes very slow, etc). Unplug the ethernet cable from the DVR and all is instantly well again.
There doesn't seem to be any issue with streaming over the network itself, because live TV works fine.
My networking skills are fair to middling. Any of you gurus out there know what I am doing wrong? I poked around in the modem's settings and nothing jumps out at me as a possible fix. Does the DVR only work over coax?
Thanks in advance for any help.
