question about fios tv hook up

does anyone see a problem with this bedroom set up.

i am going to be getting rid of the small tv in one of the bedrooms and placing a computer in its spot. the computer will have a cable tv tuner card in it. does fios tvs basic digital sd receiver have one of those connections for RG6 output. i am assuming i should be able to run it into the computers tv tuner and tune to channel 3 or 4 and switch the channel with the fios box?

nevermind, i guess it will not matter, just realized the card i purchased today has svideo and composite input adapter.
