400 vs. 800Mb

Why does a 400Mb connection to my LaCie external drive work when an 800Mb one doesn't? With 800Mb connection my captured clips played back too fast and without audio.

That one I've never heard before. Are you trying to use USB2? You shouldn't have any problems with FireWire 400 or 800. USB can't be used for any kind of editing.

No USB. Maybe my LaCie is a piece of crap like many others.

<<<Maybe my LaCie is a piece of crap like many others.>>>

Well, maybe. They don't all fail, you know.

While I do believe you that this happens, it is a little outside the normal cause and effect streams. It reminds me of the punchline to a joke:

...so to make my wife happy, I tightened up the license plate. Not only did the car start, but the radio started working.

I don't suppose you have the opportunity to try this drive on another Mac?
