To the best of my knowledge, Hauppauge does not make high definition TV tuners. The resolution of 1600x1200 is just how big the image can go while still be clear (sort of). When you record TV with the 350, it's not like it's a special file format, it's just a normal AVI (well, the way I have it set, you can change it, if you like)...it does come with output cables to connect your computer to the input of a TV. The TV Tuner itself has a few output connectors, so you should be all set there.
