Disable the possibility of using autoplay feature

This is an important problem.
I allow videos in all comments and content in my site. I found that some users add videos (usually videoclips or music from youtube) with the autoplay feature, usually with witdth and height 0, so the video is not visible, this way you hear some background music automatically.

Some other users find this annoying. There's an additional problem, because if you open the page using a mobile device, your 3G monthly data quota may be considerably decreased.

That's why I think that the autoplay should be a configurable option from the VideoFilter Input Formats settings, set to FALSE as default.
Another possible solution would be adding a "Add autoplay on videos" permission configurable per role.

I'm using drupal version 6.

I hope you can find a solution :)
Thanks.

This simple patch adds an extra option to the "autplay preset" in the configuration window of the Input format settings, called "Autoplay disabled".

This is the D7 version of the patch.
I hope you can consider this small feature, please.

I feel like this could cause confusion for some users when they try insert video with autoplay. We have to make sure if we disable Autoplay option in settings, we do that same thing on the dialog form as well (hide Autoplay option).
