Just wondering if I need an in-wall rated (CL3 or something like that) HDMI cable for stuff like home theater. I think it may differ from place to place. Also, does this apply to other AV cables such as component and RCA audio cables? Thanks in advance.

Here is an explanation for the different ratings in accordance to the NEC (National Electrical Code) and the consensus standard NFPA 70.

The major difference is the size of the wires and the condition of the insulation (flame resistant etc).

If your house is burning down because the flames started in a cable raceway and you used the wrong cable in accordance to code then the insurance will fight the claim.

If you wire free air (inside the room) then a regular HDMI cable will do the trick. For all inside wall routes I recommend you consult the code to determine the correct classification.

There is no difference in signal quality as long as you keep an eye on the length of the cable. I used a 50ft HDMI cable free air and had no problems with the signal quality. In case you want to go longer take a look at a repeater like this one here:

Then you can reach up to 164 ft total length.
