simple HDTV question.

If you have an HDMI out on your Hi/Def Sattelite reciever-and a HDMI in on your Hi/Def TV-thats the best way to go. It all depends on your outputs and inputs................

HDMI
DVI
Component

These are the three choices that you are most likely to have with a CATV/SAT receiver and some DVD players. All three connections support HD.

Good luck!

If you are talking about from your dish to the SAT receiver the best HD coax I have used is the Audioquest RG-6 3. 90% sheilded and silver conductor and sheild. As for after the box, like the other post says, it depends on the TV and box. If you are using a fixed pixel design you will want to use a DVI or HDMI. (DVI is better) and I love Audioquest for these too. If you have a CRT TV or projector and your SAT outputs uncompressed HD over component or RGB I would do these over HDMI. (HDMI and DVI are over rated) If you do the Component or RGB hookup the best cable I have ever used is Transparent.

Krelldog is right however the differences may be slight depending on equipment. Component to compenent can be excellent. Also DVI supports hi-def.

Component cabling does not support HD as well as DVI or HDMI.
Using component, you convert from digital to analog at the box, then analog to digital in the TV. DVI or HDMI keep it digital.
Using HDMI or DVI also allows the aspect ratio to change automatically - a very nice feature.
