I suspect that will be too large to send in a single email. Did the DVD pass through a PC at some point (i.e. was it edited on a PC?) If so you can use the software involved to output a file.
You can also rip the video from the dvd and send. If you rip individual short films you might get away with sending. YOu could do this and check the size. Alternatively consider posting them on a website/online somewhere or you could put them on an ftp site. You could even put them in a peer-to-peer sharing software folder and share them with your friends that way!
