HQ for EVERY video on YouTube

[Temper]

A lot of videos don't have an HQ icon to watch them in HQ. But it doesn't mean you can't watch them in HQ. You just type "&fmt=18" at the end of the adress and you'll watch every clip in HD.

For example:

You have a video which don't have that option: no hotlinking
And here you go with the parameter added at the end of the adress: no hotlinking
Check it for yourselves to make sure it works. It also works great for songs, audio quality improves a lot too of course.

And sorry if it's the wrong forum for that but it seemed the best to put it here.
do not ask for rep it will lose you points
