Five episodes is a nice sentiment, but the other 247 episodes would be significantly nicer. Really, putting them on Hulu would be the best way to go about it, but let's start with baby steps. I mean, honestly, the show's been relegated to The Cooking Channel, so it's not like ratings are an issue anymore.
Of course, you could also put Seasons 3-14 on DVD, too. Or make Seasons 1-12 available on iTunes. Or maybe Netflix. Seriously - there's a lot you could do to make Good Eats more widely available. But I guess five episodes is better than nothing.
