Beginners video capture help

[asthmaticsnail]

Hi I am looking for a way to capture video only from a wohler chimney camera that only outputs video in composite to a laptop, netbook or tablet pc. I also need to be able to view this video in full screen while recording in a reasonable quality.
A few years ago I tried a dazzle usb card but I could only manage to view the video in a small screen on my laptop so was not suitable. At the moment I am using a small tv and dvd recorder then taking the surveys back to the office ripping the dvd and recording it to another dvd.
Are there anyother ways? If so what software, equipment and performance from a computer would I require.

Any help would be greatly appreciated.

Thanks
Will
