I have to say I'm a little intimidated by the range of settings on the XL2. Is there a book or some other resource someone can point me too on understanding and fine tuning the settings?

Run, don't walk, to the XL2 Feature Tour video at DV Creators:

You might want to try a DVD called "The Ultimate guide to the Canon XL2" They have it at B&H and other fine retailers. Between that and the link Chris mentioned, you should be well informed after it all sinks in. ;)

Thanks much.
