512MB won't get you far with hdtv. It won't even get you 5 minutes
worth. Needless to say, you'd need at least a few GB of dedicated ram
to even bother with it. At least ram is cheap now as you've pointed
out (especially if you take advantage of MIR's). After seeing how
much money I was wasting every month in my electric bill just by not
setting a sleep timeout on my harddrives, ram is the only place I'd
want any caching like that to take place if I were interested in
buffering live tv.
