I will be mounting my new Samsung 46" LCD on the wall and running the wires inside the wall and out the bottom.

This is a very simple procedure in my opinion, but perhaps I am missing something. I see people spending hundreds of dolalrs to pay someone to do this.

So aside from making sure I hit the studs, are there any other concerns? Should each wire be seperated from the next (not touching), or can they all just run down the wall inside without a worry?

I will be running the Power cord from the TV, (2) HDMIs, (1) DVI and (2) sets of red, yellow and white (for Wii and Gamecube).

Thanks!

a) don't run the power cord through the wall, this is a fire hazard. there are a couple of threads about this in the LCD forum giving several alternatives. search for power cables or something like that.

b) if you do run the power through the wall, run it down a different stud than all the other wires. running a power cable parallel to other cables (especially speaker wires, or non-digital cables) can create an interference or something. I think you are supposed to keep them at least a foot (or was it a meter) apart.

How is running the power cord a fire hazard? One end of it wil be plugged into the TV, which will be on the outside of the wall. The other end will come out of the bottom of the wall and plug into an outlet. I am not using an extension cords in the wall, and there will be no break in the cord.

Running any wires inside the walls that are not certified as in-wall is technically against code. In-wall certified cables have much thicker insulation, and generally are fire retardant so as to avoid acting like a fuse that spreads fire from room to room.

Given the short runs for the TV, it is very unlikely that a problem will develop. However, if you chose to run the AC wire through the wall and something should happen related to that wire, your insurance company can potentially deny the claim on the basis that the wiring wasn't up to code. The simple solution is to mount an AC outlet on the wall behind the TV. Ideally you should have a licensed electrician do this, unless you are familiar with AC wiring. It shouldn't cost much more than $100 or so to get someone to do this, unless you don't have an outlet under the TV (in which case they'll need to go through some studs).

With low voltage cables like HDMI, the only real risk is the cable acts as a fuse. MonoPrice sells in-wall certified HDMI cables, as well as single and dual HDMI wall plates. I did my own work, using electrical boxes purchased at home depot, two Monoprice HDMI wall plates, 2 in-wall certified HDMI cables. Total cost is about $50. I prefer the finished look, so I put wall plates behind the TV and down near the floor.

Other than the advice above about keeping the AC and signal cables a foot apart, you should be good to go.

I have unfinished space behind my set in the basement, and there is an outlet on the back side of the wall. I had planned to run the power cord (and all other cables) through a small hole in the drywall and then over to the outlet. I realize it's a state-specific thing, but would this be considered against code? The wires wouldn't actually be inside a wall, just through it.

I think it would be.

Again, 99.9% of the time you will not have a problem with it. BUT, if there IS some sort of fire in either of the rooms, the firs may travel through the cord (which is less likely to happen with an in-wall rated cable) to the other room, torching your whole house. If the insurance company gets a hold of this info, they may try to not pay your insurance.

So the question you have to ask yourself is $20 and a little creativity worth giving the insurance company an out of something happens?
