I have no idea myself (No experience with JDirect either). The problem we
have is that our recordings are now 500mb instead of 250mb and we FTP each
file at least once over the network. So you can imagine that makes quite a
bit of extra network traffic. The thing is this happens using QT's supplied
sample code. It's not like I am doing anything special..

Thanks for the idea anyway.
