Flash CS3 transparent background

O.k. I have been trying for weeks on this project but I know it can be done. I shot a subject in front of a green screen and he wants a Flash movie of just him (the subject) and no background. I told him it could be done. I shot a 1 mintue video using the old DV rack to make the green screen fairly good. I imported the avi clip to Premiere Pro 2 and used the chromakey ( Color key on some tries) to remove the green screen whereas the background was black. I saved it and exported it as a quicktime movie, animation compressor codec, millions of colors square pix. Then I used Flash CS3 and imported the video to the library by On2 VP6 codec with the alpha channel selected. I created two layers, layer 1 a jpeg image. I highlighted layer 2, dragged the FLV playback to the stage and made sure layer 2 was about layer 1. I saved and tested it but the background is still there. I have tried several ways; saved a flash file from Premiere Pro2 and imported it with CS3 Flash encoder following the same steps. I even loaded and older version of PPro 1.0 and followed a tutorial exactly. The FLV plays well but I can't see the image from layer 1 because the background is black and not transparent. All I want is a transparent background where the subject is there without a background. I have Ultra 2, Visual Communicator, I can make a background of anything but I can't seem to make a background transparent!

Sorry for the long post but I have been at this for days. I have posted this on three other forums (one of which I pay a monthy fee for expert service) that all tell me to do the same thing. I know it must be something small but somebody would be my hero if they could help me with this one! Thank you - Art

In order to get that alpha channel into the MOV, your settings need to
be configured for millions+ (not just millions). Can you doublecheck on
that aspect?

There's also the "Encode alpha channel" setting in the Import Video
wizard. That's what carries the alpha channel into the FLV. You might
already be doing these, but we have to start somewhere, right? :) We
should be able to figure this out.

With me starting at the very bottom is good! I did not try Millions + I did use the Encode alpha channel in the import wizard. I'll try now. BTW the 2ns track shows through as a background as the first track is keyed in premiere pro.

Yes, several times. That is the tutorial I loaded a previous version of Premiere Pro I tried to export quicktime and FLV. I get a good key. The background is totally black, just not transparent when I transfer it to Flash CS3

Thanks
