What's the best way or device to play DVDs in my car (audio only is fine). Have a regular CD player only.

Natalya Sydney: if you typed your question on a laptop you already have most of the hardware, next thing to get is a head unit with line in and a cable with two 3.5 mm stereo jacks (one end plugs into the headphone adaptor on the laptop and the other into the head unit) You will have dvd screen with audio running thru the cars audio, buy a 12 / 240 volt inverter as well if you are planning to use the laptop for any lenghth of time
