  There's an automated way of doing this. I've written a bash script that will find flash video files in the current directory *REGARDLESS OF THE NAME*, and move them over to a specified directory with sequential names, i.e. mm000.flv, mm001.flv, mm002.flv, etc. Here's the setup...

1. mkdir ~/mvflv
2. save the script below as ~/bin/mvflv and make it executable. This bash script is released under GPL version 2. You don't know me, so you may want to wade through the code to ensure that it doesn't do anything nasty, especially in the backtick expansions. (I originally wrote the decrement(), increment(), and getnextversion() functions for use with my system backups, so that they would be sequentially numbered).
3. cd to either /tmp or Firefox's Cache directory and execute mvflv The script lists each file it moves into ~/flvfiles
