SF proper you can get busted for any cable that is not CL2/3 behind the finish. And you should elsewhere as well, but.... Nor will you be able to put PVC in the walls. (Local SF code prohibits use unless in concrete or below grade...) Nor would you be able to use smurf - same reason.
Normally what I do is use 1.5 -2" liquid tight flex, and strip the outer sheath off. Sounds hokey, but regular flex the curigations are too hard to get certain connectors through. Strip the jacket off and there is no beef about it being in the wall AND it is way easier to get through the framing! Trust me! It is much more flexible, and can make tighter radius bends. (Put the connectors on first - they hold the whole thing together... Or often I tape up the end to keep it from fraying.)
As for field termination - that is a NO! HDMI is fickle enough - it would eat way too much time, and I doubt you could easiely obtain the connectors, or get it to work right if you did.....
Distance past 15' the signal degrades, and unless you are paying a premium for the cable you risk it not sync'ing, or the equipment deciding what the max data will go through it.
The last one I did at 30' worked - but after two cables. The first being one that had modular ends that were connected after it being pulled - sounded neat, but worthless as it did not survive pulling it..... FYI this stuff is not very robust - bend it too much - forget it. And does not even do very well for long periods on those swing arm mounts everyone loves for those big wall mounted jobs.
My neighbor across the street works for a locally well known AV company that only does the big $$$ stuff. He says he will not even bother with distances over 15' due to the risk of signal loss, etc. And uses Baluns on every job over 15', as the cost of good cables is about 50% of the cost of baluns, (we are talking about people to whom money is no object...) and they start to equal the cost of good cables at ~30+'. At 50' they are equal to the cost of baluns, that still run the risk of not working....

There are also active signal boosted cables avilable....
Most often the audio quipment and the tuner/dvd will handle the audio portion, although sets of RG-6U can be run to sub's or powered speakers with F - RCA adaptors, or just plain ol' (also CL2/3) speaker cable to say a center speaker, or L/R in a TV cabinet. And if you're up to all of this pull some wire for IR eyes, and flashers too.
FYI - I watch TV on this very 17" monitor I am looking at now.... With the basic cable stations that came on my modem hook up.... 75% of which (that are in english) are PBS. :grin:
