Progressive FLV's / Client Side Caching

Hey All, I’m running into a strange issue when downloading FLV’s. The FLV’s are not being cached on the client side.

What I’m doing is preloading FLV’s, using a URLLoading and downloading it as binary format. When I go to play the FLV’s in a FLVPlayback, they re-download. This is strange, shouldn’t they be being cached on the client side? I am downloading them progressively.

The strange thing is that at one point they were being cached correctly, but now they re-download.

The thing that bothers me is that when I do bandwidth throttling to make sure everything will play smooth, they don’t play smooth because they are re-downloading when they shouldn’t be…

any ideas?
Thanks
