CAUTION: You must use in-wall rated wires (with CL2 or CL3 rating) as this is the fire-code in many areas.
You dont have any HDMI sources now but you want to future-proof the wires. I respect that.
(Trust me - the labor to install the wires swamps the cost of the wires.)
Here is my suggestion:
- Install a long HDMI cable (2 would be better)
- Install a long SVideo cable.
- Install a long Optical cable (out from TV to receiver)
- Install Cat6 networking cable
- Install RG6
Here are my reasons:
Future proof (2 would be better) (and you really should upgrade your CATV/Sat or whatever service to HD which will give you HDMI.
You can run all your stuff with SVideo now. While component is better - its a lot more money for something you are going to abandon in favor of HDMI later. So just ignore component for now.
All HDTV programming is in 5.1 just like your DVD player. Your TV will output 5.1 sound which you must feed into your receiver. While your cable/sat box may give you the optical output - it's nice that the TV can feed sound back to your receiver.
CAT 6 NETWORKING
This is cheep and easy and I am seeing a LOT of press about internet-accessable televisions for Netflix on Demand, Google Apps, Vudo, etc. For the price - it is cheap insurance to add a Cat6 cable.
This is also cheap and easy. Simply plug an antenna to the other end, have the TV scan for channels and you may get 3,5,..10 local HD stations for free. (Use www.antennaweb.org to see where the TV towers are around your home).
WHERE TO BUY:
Go to www.bluejeanscables.com and buy a Belden based HDMI cable. It is in-wall rated, has something like a 300 lb pull strength and wont cost an arm and a leg. The owner has rolled out a 100 ft run and says he saw no issues.
(Runs of early HDMI cables over about 15 feet had issues so you dont want ultra-cheap HDMI cables for in-wall use.)
Then I would buy one of the cheaper Tatung HDMI cables for the second HDMI connection to give you flexibility.
For the Optical, Cat 6 cables go to www.monoprice.com - but try to look for in-wall rated cables. (Cat 6 is in-wall, but I'm not sure about the optical)
For the RG6 coax - go to Radio Shack. All RG6 coax is in-wall and outdoor rated.
Go to Radio Shack and buy their $2 pack of wire labels. Do a simple "A", B", "C"... label on each wire. For behind the TV - do it right behind the connector and 6-12 inches back. For behind the equipment - every foot until it disappears into the wall.
DO NOT use wall-plates with connectors. This is for techno-challenged people. Do run all your wires through electrical outlet box's (they provide strain relief) but buy blank wall plates and drill holes for the wires and cut a slit to go around the wires. This will give you a neat install, but not break the signal path.
I would separate the HDMI and Optical cables into 1 bundle, then the Coax, Cat6 and SVideo into another bundle.
(I know I gave you way too much info, but I've done this type of stuff a lot and made mistakes/regrets later.)
