Nothing that you run today will make much sense in a few years! Today, the
only way I know of to distribute HDTV is to use component cables or HMDI, I
have no clue as to the range of either. Soon, I suspect that most AV will be
distributed wirelessly over your house WiFi network.

A few years back people were installing fiber optic cables, we all know how
useful that turned out to be, so it is hard to predict the future.

So I would suggest a central wiring closet, big conduits and whatever wiring
makes sense for the system you have today. My guess is that today, most
people have receivers or DVR's in each room with a TV, so RG6 is all that
makes sense for AV (to get signal from where the cable or the dish enters
the house to where you want it to go). Some rooms may have remote speakers,
so speaker cable would be useful, and receivers with multi-room capability
may have some form of wired remote. TiVo with HMO or TiVo to go, can
distribute AV, but I think that is done over the LAN, so CAT6 makes sense
(for now).

Another consideration is the possibility of powered speakers in every room
(and outside) with docks for iPods or satellite radio receivers - then you
would need power at the speaker locations, and away to move the signal to
the speakers.

Then of course is the big screen inflatable projection TV by the pool and
the hottub with built in plasma to consider .......
