Yes, tape is much cheaper but there are some benefits storing iMovie 
projects as data files on DVDs or removable Firewire disks:

-The iMovie project folder contents may be stored "unflattened", i.e. 
you can remove titles and transitions to reveal underlying original 
footage.

-Data files on HDs and DVDs have more robust error correction on more 
robust media compared to DV/D8 tapes which are prone to dropouts.

-Speed. Transferring 1 hour from/to a tape takes 1 hour (3.6 MB/s) 
whereas at least a FW drive can be much quicker (at least 25 MB/s?). 
How fast are DVD drives?
