I have just had a few hr 24s put in, and they are connected to my hr 20 in the basement which was connected to an Ethernet switch, then back into my router. When the tech did the install, he connected the Ethernet to a deca adapter and into the coax. Any reason I can't connect that deca to my Ethernet switch and then the switch to the DVD? I was thinking this would allow simultaneous mrv and downloadability for on demand. I was going to experiment. But thought I'd ask here first. Thanks.
