Replay A/V should be able to get these .SWF videos if you check the following options in the URL finder:
-Show SWF (flash animation) files
-Show cached audio/video

It didn't really work for me... so I've contacted the developer. Hopefully the bug will be fixed very soon.

p.s.
I had no any problem getting .SWF videos from the cache folder of my Internet Explorer and Firefox.
