You want simple?
Install nautilus-image-converter
It adds two context menu items in nautlius so you can right click and choose "Resize Image".
(The other is "Rotate Image").
You can do a whole directory of images in one go if you like and you don't even have to open up an application to do so.
Very simple to use, very simple to configure.

If you're just doing a couple of images, most image editors in Ubuntu (Gimp, F-Spot, etc) will let you do a basic resize.
If you want to edit tens, hundreds or thousands of images, I prefer Phatch. Phatch is a GUI-based batch photo editor that will let you perform a whole load of transformations on images. sudo apt-get install phatch

kdenlive is (in my experience) the easiest software which will allow you to perform that task in a few steps and without problems. Even so, the OpenShot Video Editor project is also useful but it yet needs lots of hard work to get closer to the kdenlive.
Here are a screenshot of the kdenlive and openshot respectively:
I would suggest you to take a look ...

Some are for legal reasons - some video/audio formats require further license agreements or don't quite fit under the Ubuntu license schema. You can read more about this on the Ubuntu Wiki: Restricted Formats page.
I know that Ubuntu Studio comes with a lot of these codecs and "drivers" already installed. However for an average desktop user it's a lot of ...

This procedure works fine with standard keyboard keys. ...

There you will see a header called sound (Expand it if needed), and remove the key combinations you want in VLC from there (You can disable them by clicking on the item and then ...

mogrify -resize 50% *png # keep image aspect ratio

You are right, the ffmpeg packages in Ubuntu 10.04 and 10.10 do not support video filters. If you use Ubuntu 10.10, you can add unofficial packages from the Debian Multimedia Project and install their ffmpeg version (you should not do this if you use Ubuntu 10.04, there are too many conflicts with older packages. Also do not combine those packages with ...

GIMP is probably the easiest way, since it has a fairly simple UI for such common tasks. All you have to do is open up your image and go to Image → Image Size and then change accordingly. There are ways to do batch resizing using the GIMP as well, but I don't know them by heart.

Drag-and-drop works brilliantly in Unity (in 11.04). You can drag and drop both directly onto open windows, or onto the applications launcher.

The multimedia keybindings are stored in $HOME/.gconf/apps/gnome_settings_daemon/keybindings/%gconf.xml. But note that this directory only exists if you changed any of the values -- keys with their default value (e.g. play = XF86Audioplay) are not stored.
