that wont work, there are video converters for flash but none of them work well. unfortunatly there is no real way of converting the files form shockwave flash. the only thing i can suggest is to get a video capture for your desk top make the flash full screen and then edit it with some video software...
the problem with importing an swf into flash is it breaks up the elements frame by frame making a huge file and a file that isnt play friendly to most animations.
ive been working on some home star runner conversions with no luck...
