I'll agree with BEcky here, although for iPod, I actaully allow FCP to encode it directly for iPod... which means that even if you port out to your TV, it will look rather impressive.

(I honestly think this is the direction that the industry will soon go, anyway, so I'm just ahead of the game.)

Here's a secret.

FCP will encode an iPod file with and .m4v extension, but if you rename the file .mp4, anything can play it.

it's just Apple's way of trying to confuse the end user.
