I have a soundblaster live USB card… got it for like 30.00 or so @ bestbuy
They also have turtle beach units… the soundblaster supports 5.1 though :tup: Oh, and if you buy locally… go to compusa… they’re going out of buisness and selling lots of stuff cheep. Got a 22" widscreen LCD for like 300 (retails for around 400 IIRC)
as for the DVD, I’m not sure… did you try looking on http://www.mp3car.com/ ? I’ve ordered a few things for my carputer but have yet to even attempet to put it together yet, let alone take it out of the box. Post pics when your done, I’d like to see it
