download YouTube videos

I stumbled across this site freeuse.in that claims to allow you to download YouTube videos. I tried it out but for some reason it caps the download to 1.9MB which is nothing for HQ videos. Is this a problem with the website or my CrapBerry? Anyone tried this site and had success? Any input is greatly appreciated. Thanks!

Edit: I should clarify that I am using Opera Mini so the download limit in the BlackBerry browser is not a factor here. I've downloaded large files, ie the engadget show, through OM with no problems.
