You could use dd with an estimated file size, but you can as well use a
short shell script that utilizes $! to get at a backgrounded PID, as
already shown in the other reply.

One could as well write a timed version of cat within a few minutes.
If anyone is interested I can whip one up. All it takes is to call
"alarm()" before starting to copy.

This is due to the DVD quality to which it defaults. You can adjust that 
with the bitrate parameters in the sysfs interface.
