Hey I need help choosing one of these HD cameras. I want a camera that shoots in 16:9, H.264 - 1280 x 720 - 30 fps out of this list, most of them shoot in that and claim to shoot 720p but do they reallly? Prefereably I want it to have a clear image aswell like Chad Vader season 3 on youtube

Canon Power shot (Link) 14.1megapixels shoots in H.264 1280x720 but is that HD?

And then we have the Sony Cybershot DSC T99, (I can get it on ebay new for around 210)
Claims to have HD MP4 movie

So which is the best quality and 16:9 wise? THANKS
