Please help me - I'm a total newb! I live in a very rural area and for Internet access I'm using my cell phone tethered to my PC. I then share that Internet connection (as flaky and as slow as it is) across my Ethernet network using a switch. We just had DirecTV installed (but apparently not well) with the Whole-Home DVR option with just one HR24 and then two non-DVR receivers. I asked the installer how to hook up the receivers to my network (I have a ton of movies and recorded WMC TV files on my PC). He said that I'd need an adapter to go from coax to ethernet (or vice versa) and that I could buy it online. He also said not to plug my Ethernet into my receiver or it would mess up my whole-home DVR. I'm confused as to what adapter I need. Could someone please point me to a specific Ebay or Amazon listing? I would appreciate it. (I just don't get it... DECA? Cinema kit? Powered? Not Powered?) Then, I assume I'm just going to go from my Ethernet switch into the DirecTV Coax splitter, right? Then I ought to be able to see the DVR on my network, assuming I can give it an IP address. Sorry to be such a newb... I promise to read more and start understanding this stuff - but in the meantime, my kids can only watch their old and beloved (pre-DirecTV) recorded TV on my PC until I figure out how to stream to these receivers across my network. I need them off my computer!
