Watching Apple HiDef trailers in Linux through a browser is problematic, if not downright impossible. So the answer is just to download them.

1. Go to Apple Movie Trailers, right click on the link to the trailer and copy.

2. In a terminal type:

wget -U 'Quicktime/7.6.2'

3. Add a space at the end and then past the URL

4. This is the important bit, move the cursor back to before the resolution of the trailer, i.e. He you need to add a h, i.e.

Example 1 (before adding an h)

wget -U 'Quicktime/7.6.2'

Example 2 (after adding the h)

wget -U 'Quicktime/7.6.2'

5. Hit return and the file downloads in to the main root of your home directory.

Difficult eh...

Wget Timestamping

Timestamping (-N option) can be used (especially in an automated script) to only download a file if it has changed (a bit like rsync backing up). You can download a file so that it keeps its date of modification.

To check the date...

 wget --spider -S -U 'Quicktime/7.6.2'

...but it will only download it if it has changed.
