So I bought my Flip video camera and made a quickie video to use as a test.

I inserted the Video Camera into the USB of my computer and then
the software opened and I loaded it on the computer.

Cool! ... or so I thought.
Time to edit. The version of Muvee that comes with it is limited and also
I couldn't add titles.

For me titles were an issue so I figured well the camera is creating an
AVI file and Windows movie maker should be able to deal with that but noooooo.

When I imported the file into Windows Movie Maker only the audio would open.
So I drove myself nuts looking for a solution and finally I found it.

Ready? Here it is:

Roger's easy fix to editing Flip Videos with Windows Movie Maker:

Edit the Flip video AVI file in the Flip Video provided software only as much as clipping the unwanted intro or ending if need be and then use that software to make or save it as a "Movie". It seems that the codecs for the original AVI files aren't the same as needed by Windows Movie Maker.

Save it to a folder and then open Windows Movie Maker and then open the saved "movie" version for further editing. That's the trick...
Took me 2 1/2 hours to figure that one out. Damn!
Finally the video opens and so does the audio. Neat Nice!
