Wireless bridge at home

Dear all,

I wonder if you could help me out with a following setup.

Currently I have:

an ADSL connection (ends with an ADSL modem)
a Linksys AP connected to it
Which provides me with a wireless network at my home.

What I am trying to do:

I need to have an internet connection where my TV stands. Unfortunately, the
device I need to have an internet connection to is not and cannot be Wifi
compliant (its a satelite tuner). Thus I am thinking of buying the second
AP, placing it where my TV stands, connecting it with an ethernet cable to
my sat tuner, and connecting it through Wifi to my ADSL modem in another
room. My question is simple- is this possible at all, and if yes, how?

Thank you in advance,

Liudvikas
