I bought an Archos 3 2 wks ago specifically for video(tv) out as quoted in reviews.
I purchased a cable from Datamind, whose link is http://www.data-mind.co.uk/acatalog/Archos_3.html
My next problem-will it work?
Phoned Archos tech several times, as usual-next to useless. 60% of responses said "the Archos 3 doesn't doesn't allow for video out"!. Why then, I asked does it have a tv setting for PAL etc when scrolling down to bottom of "settings"?
Anyhow, here's how to do it if you're struggling as I was.
1) buy lead from Datamind (archos site did had them for sale but were charging a fortune for p+p, now they're not even selling them!)
2) plug in the leads. Simple-3mm jack to red/white phono & mini-usb to black phono (video-usually yellow but who cares if it works!)
3) turn on Archos 3, enter settings (bottom, 3rd from left) and use scroll wheel to bottom for TV & set for PAL.
4) Open up video as you would normally and whilst rew/play,pause/ffwd on screen touch the top left of the screen (little tv icon). Video should now be playing through your tv or other device!
Sorry for going on but I hope this is useful (unlike Archos Tech!)
