Thanks all. All answers helped me, thanks a lot. Cheers :)

use the same process as with google autosuggest in yt a;phabet soup....
yt doesn't have the same rules within itself but to rank in google it does... so use jaaxy after autosuggest research and find the low competition keywords...
i use keyword researcher pro - paid tool covers google - amazon and yt with google questions and related....
bit clunky to get the metrics but very usable
have fun
