Thanks but where I live the only internet is dial-up unless you want to pay a high price for satellite.
When all the stations went to digital, I just kept using my old outside antenna and it seemed to work fine. The only station I lost was the local PBS which I normally don’t watch except for those odd shows which actually are extraordinary.
you could get a digital antenna, it might pick up more channels (and better video quality)
you could also try to dnload tv shows via a torrent (i use http://www.utorrent.com/ ).
my favorite site for tv shows is: http://eztv.it/
there is also an entry for sherlock: http://eztv.it/shows/376/sherlock/
and a rather long list of series: http://eztv.it/showlist/
