In Europe a cable that has a 3.5mm 4 element mini jack on one end (as described by Mike as "round, with four connectors----tip, and 3 bands") and 3 RCA plugs the other (red, white, yellow) is about $5 - they must be available Stateside. I'm guessing the 2 pin flat plug is to do with the in line on/off switch? If using a non Archos camera I imagine the record button on the touch screen could be used, is that right, Mike?

Pete, I am pretty sure the flat plug is power, and maybe switch leads.
Also, pretty sure you hit the nail on the head for the round pin, although it looks like about 1/8th inch in diameter, IIRC, that is pretty equal to a 2.5mm-----but I may be wrong here.
John, Archos offers an adapter cord with the standard red, white, yellow RCA jacks on one end, and the round plug on the other. However, this is advertised as an output to TV device. Click this link, scroll down to the cord.
The photo shows a plug exactly like the one on the camera, so my
guess is that it could be plugged into the travel adapter, and a different camera hooked up, might take a RCA double female, or 3. My second
guess, is that the camera would need to have internal power.

Unfortunately, there is no photo of the plug---
Good luck.
