What is the most versatile video converter for an Apple Mac running OSX?

[SheerGold]

I have some videos that I want to put on an Archos AV500. The AV500 is a small portable video player with a 4" screen.

Some of the videos were downloaded from the web.
Some are actual DVD's.
The videos are in a wide range of formats, many of which do not play on the Archos AV500.

So I am looking for a video converter that is very versatile. Plus hopefully one that's also fast. Obviously a free one would be preferable to one that I have to pay for.

I have tried ffmpegX and iSquint. But neither works with all files that I need to convert.

All advice appreciated.

Thanks.

Visualhub, if you can get a hold of it.

mpeg streamclip. you can open almost anything in it then go File>Make Quicktime.

from there you can pick .H274, MPEG4, almost anything

I agreed VisualHub or the free iSquint, work awesome. :)
