do you know a way to run 2 television sets on the same digital box with just one smart card.?

Question

specificly on dth services(like direct tv)

Answer 1

you would need to connect a splitter to the output of the box going to both televisions. the drawback to this is it would be displaying the same channel on both TVs.

Answer 2

yes, but not to get differnt channels on each tv.
just before it hits your tv use a y splitter, and go one wire to each tv
if you need, you can get a remote extender, so you can use a remote from another room to change the channels.
