FireWorks LOVES Flash 5 and vice versa, so your problem shouldn't be with your png's. Try looking at the format of the problem movies it could be a problem with your actionscript or other.. I couldn't tell you without more info.. I know how ever that Flash 5 was built for FireWorks.. I am stuck with Adobe Photoshop and Flash loves to **** with my graphics anyway.. pngs should work no differently than jpgs in your movie so the problem is somewhere else.. vector graphics are only useful for line art,clip art, ect... so in other words.....

NO you were not wrong to think png's are cool.. your problem is most likely something else..

I hope this helps
