Answers to a couple of things...
1. I use Fraps, as I've found too many other screen-captures tend to be broken or inconvenient in assorted and imaginative ways. Fraps at least has a consistent interface and I use a script to convert the files into a less offensive format and put them in the relevant directories.
3. Don't clear keybindings but rather bind them to some obscure key sequence you'd never actually use: something with a couple of modifier keys should do. Trouble is, if the game finds out that a key has been cleared when it starts, it "fixes" it by restoring it to the default setting.
