file.flv when the reocord file is good to be saved else i delete it with
delete.asp file so the problem is
when i'm trying to play the file that i just saved cause it playing the old
record not the new one but after some time i can play the new for example after
2 minutes is any one have the same problem.

Since FMS doesn't cache files on the client, how are you calling your "playing"
SWF? You could try a cache buster when you call it like:

this.loadMovie("playing.swf?vid="+random(1000));

Or, do that with your SS script if you're getting the FLVs that way. HTH...:)
