I am wanting to capture satellite tv on to my computer to make music dvds. i will be playing back on my xbox so im not sure it can play high def, i would also like to capture my xbox game play for youtube but its the dvds that is most important. so which standard def external capture card is of good quality if that's what i need and do they play back in exact quality it was recorded from. i was going to buy a dvd recorder but was looking into this as well. thanks
