Hello all.
Finishing my basement.
My wife wants a 50+" tv on the basement wall ..."whenever I'm done." We're NOT trying to make a "media screening room" with perfect seating and acoustics. Just a big tv with some comfy sofas.

My question is, is it worth the effort to extend the cable tv wire to this location from the main floor tv/cable/dvr box? Or are today's tvs and perhaps a dvr box upgrade so fantastic that I can just as well do everything via my local wifi network in the house? I haven't stayed current with the latest A/V tech and I just don't want to go through all the trouble to run the cable wire for nothing.

Related follow up question: my wife wants surround-sound and is asking me to install speakers in the walls and ceiling. Is this sort of thing done anymore? or strictly a 1990's thing? Again, I don't want to install something that is obsolete or even regrettable.

Experienced opinions greatly appreciated.
Online references and guides appreciated too.
Thanks
Theodore
