But at least you are not one of those audiophiles that claims every interconnect sounds different.
It is a RG-59 or RG-6/u most likely. All cables in these Component bundles are RG-59 & RG-6/U http://www.monoprice.com/products/subdepartment.asp?c_id=102&cp_id=10235
Any Digital audio cable out there is going to be RG-6/u. BTW, 50 Ohm Coax is RG-58, previously used for Thinnet or Token-Ring networking setup http://en.wikipedia.org/wiki/RG-58
Not a good choice for audio or video, same goes for RG-11 or RG-8. The later is a different topic, but had to add that, since the mistake of stating that coax cable is 50 ohm, but not stated which one was being talked about.
Personally if I was doing it, I would pull one run of Coax for OTA, two Cat-5e or Cat-6 (one for networking, one for hdmi), two runs of RG-6 for audio if hanging a sound bar also if not always going to use the home theater. Run everything back to a closet for the equipment, or rack in a cabinet, if the equipment is going to be next to where the tv is, but say bookshelves on either side.
Octopus cable is best to be used in these situations, since it is a one cable pull, so that you are not having to deal with multiple boxes or spools of cable and having to tape the lines at so many feet, to keep the bundle neat and tight, while pulling through Smurf tube vs. conduit. Only time I would use conduit, is if required for fire reasons between floors, and then having to use either "monkey poop, which is like Plumbers putty, that is used for fire stop, or Big stuff fire stop at the end, if the run goes between multiple floors of the structure.
Now the even better thing to do, if you are hanging the flat panel up, is place a panel of 1/2" or 3/4" plywood painted behind the tv, that is attached by screws, so that you can remove it if you ever have to redo or add to the wires for some reason down the road, if you did not use Smurf tube or Conduit for the pull.
No one really knows what the future will hold, but we all know that Copper is still here to stay for a long time down the road, but now we are seeing Consumer network switches with Fiber Backhaul finally coming down in price (Netgear GS110 8 10/100/1000 ethernet ports, POE & 2x2GB Fiber interconnect) around $130. That adds to the fact, that it would add to a reason pulling Fiber at the a/v equipment location if you do go with one of these switches at that point for gear and the ethernet connect where the flat panel is hung up.
I may be actually getting two of the Netgear GS110's, so that I would not only be future proofed at this time for the future, but also so I can move my network to the next step for media streaming, and relieve some of the congestion off of the backhaul between the upstairs switch that has a A/P on it, to the downstairs switch that is handling everything going to the router.
