span DVDs help

[biferi]

I have a lot of video files I use for video editting and they are all around 8 GB

I can burn eatch file to a Blank DVD that is no proplem.

But I have to switch DVDs by hand and burn the next file to a new DVD.

Juts to back them up so I keep every video file as VOB or avi or mpg or what ever.

Is there a FREE program that will let me put all my files into it and wen I go to burn them it will Span the CDs or DVDs and just keep asking me for a new CD or DVD
