HDTV with DirecTV

by Julie Dereschuk / May 27, 2008 8:32 AM PDT

We've just finished a room and are hooking up a new HDTV with our existing DirecTV service. We moved the existing hookup, before the walls went up, to a new location in the room. The DirecTV installation guy came out yesterday and told me they can't hook it up because we wired with standard coax cable (instead of the heavier duty stuff). But, our friend that hooked it up works in the industry (sells and installs AV/electronic equipment to business), said it's not necessary--coax works just fine. Any thoughts on this? Anyone had to battle with DirecTV or other satellite network for the same reason and had luck doing so? Wondering if we'll have to try to fish new cable through the walls or worse.

(NT) RG-6 is what's needed for satellite. Got that?

Not according to the guy that ran our wires... He said he runs hdtv in his house with coax, and that even some of his businesses use CAT5 (am I using the right name/number?). He told me even people in his industry have misconceptions about hdtv and digital signals, etc.

Coax (analog) is used from a satellite receiver to the dish for all types of service and it must be RG-6. From the receiver to the TV must be HDMI (fully digital) cable for High-Def, or the 3 component cables (analog) with two audio. You cannot run a fully digital signal (HDMI) over coax of any kind. If you have a dish and will be using a receiver at the TV you will use RG-6 to connect the dish to the receiver.

CAT-5 is a fully digital signal and it is used between computers and routers, not TVs.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
