Warning: disk space is low

Hi there,
trying to transcode I receive the following error message: 
Warning: diskspace is low. This task needs about 674544 MB, but only 79753 MB are available.

Now, here is my df output:

salmonix@darkstar ~ $ df

My mount output:

salmonix@darkstar ~ $ mount

usbfs on /proc/bus/usb type usbfs (rw,noexec,nosuid,devmode=0664,devgid=85)
securityfs on /sys/kernel/security type securityfs (rw,noexec,nosuid,nodev)

The storage paths are all in /h.me/salmonix that is mounted on /dev/hda4 so I have no clue about this error message.

Environment: Gentoo, dvd::rip 0.98.8, installed with emerge.

Thanx!

(Otherwise: great work.)
