I am trying to get video from my Comcast DVR to my computer and eventually on my ipod. There is a family computer in my basement (where the DVR is). i was wondering, could i hook up the tv tuner to the computer in the basement, hook the other end up to the DVR, and record a show onto that computer? then send it to my computer 2 floors up? also i want a tv tuner but i am not sure which ones are good. any reccomendations? (looking for USB, under 50$?)
