Downloading commercials? How do I do that?

There's a whole bunch of ways - pick one that suits you. You actually download the film by watching it, and it is then stored in your browsers cache where you can fish it out. Alas, I can't keep a list here of every single browsers cache location on every single operating system, so if you want to get it from your cache you have to figure that out on your own (it's not hard). Here are some other options.

The really easy way: If you have Quicktime PRO you unlock Quicktime's built-in download and saving possibilities (among other features) and then it's just a matter of clicking the button that appears on the right of the toolbar. Like so:

The more plugins in your browser way: This might seem slightly geeky but can also help you when you are on other sites. If you use Firefox as your browser,
spruce that up with the greasemonkey extension, after which you can add the unembed script to it.
Now when you surf *any* site with embedded video you will notice a "download" button next to the films. Always! On every site ever. Kewl!

PC users: the Orbit Media Downloader will happily download QuickTime as well as Flash videos, and save them to wherever you like.

The really old source reading trick: There's a menu in every browser that allows you to view source. Once you've read the source of a page you can search that for the .mov extension, and find a direct link to the film, which you can then download.

Note that upgrading to Quicktime Pro can be good for other reasons as well, say for example if you'd like to put the downloaded commercial on your iPhone or iPod.
