What you using in your original assets? Don't you have the images already? Or are you just trying to rip an animated gif from someone else's SWF?

First solution, don't try to make animated gif (256 color) from jpg (millions of colors, compressed to the nines). The algo just isn't there that can calculate the best colors to use. Not only that, jpeg is rasterized, where as GIF is essentially a bit map of sorts, mapped to 256 palette code points. Apples and oranges that don't mix or get along.

Best to start with a GIF (or PNG 8 ) collection in your assets, and create the animation frame by frame. Then you can be sure to have the result you want.

There is one more thing that occurs to me, as well. DO NOT USE progressive jpeg. If you can resave the original as NOT progressive, you may have better results.

Flash exports the first frame in the SWF file as a JPEG, unless you mark a different keyframe for export by entering the #Static frame label.

1. Select File > Publish Settings, click Formats, and select JPEG Image.
2. For the JPEG filename, either use the default filename, or enter a new filename with the .jpg extension.
3. Click the JPEG tab. DimensionsEnter values for width and height in pixels for the exported bitmap image, or select Match Movie to make the JPEG image the same size as the Stage and maintain the aspect ratio of your original image.QualityDrag the slider or enter a value to control the amount of JPEG file compression. The lower the image quality, the smaller the file size, and the reverse. To determine the best compromise between size and quality, try different settings.Note: To change the object’s compression setting, use the Bitmap Properties dialog box to set the bitmap export quality per object. The default compression option in the Bitmap Properties dialog box applies the Publish Settings JPEG Quality option.
   ProgressiveShow Progressive JPEG images incrementally in a web browser, which makes images appear faster when loading with a slow network connection. Similar to interlacing in GIF and PNG images.
4. Click OK.
