What format do you recommend? In your documentation you specifically

refer to loading mpegs and AVI for stacking.

It says .mov, .mpg and AVI..

Perhaps I'm confused:

I thought .mov is a form of mpeg. I've been sticking to the .mov

format.

mpeg is actually a specific format of vidoe +/- audio.

Both .mov and .avi are containers for video and audio. They can contain all sorts of different media types, including mpeg.

QuickTime Pro won't load AVI movies without the AVI codec, so we're (hopefully

temporarily) out of luck on 10.4. I'm only mentioning

it because you mention AVI in the docs.

Your Laptop probably has third party codecs that are not installed under 10.4. For example DIVX, ON2, ZyGoVideo, 3IVX codecs may be required to play back .avi files.

I suppose that explains some of the dropouts I see in the histograms?

Nope, those depend on gain levels.
