If you want to watch flash presentations on your GP32 you could try CamStudio (freeware) from http://www.rendersoftware.com/. This will record flash on screen to avi. It supports compression codecs, though you may have to use VirtualDub afterwards. Although it sounds a bit tortuous, the results can be quite good - worth a try.
but you still need Moviepark or GPCinema to view them on the GP32. Thats the way i do it with those "Regurge" clips (where they take songs, chnge the lyrics and make a funny video (i want a fat babe....))
