cheers for your comments, yeh its a lot of fun.
@ Zero - Its pretty easy, I just grabbed the video and sound files out of my BF1942 folder and put them in to the BF2/mods/movie folder (i think - its somewhere around there) Anyway, to have the music playing as well as the video you can use Bink's "Smacker" program to splice the sound from BF1942 and the video from BF1942 together. Both games use the same file type wich is a Bink file. Bink is cool and fun to use, you can get any music and any video and put the two together for Battlefield.
