There may be such beasts, but I wouldn't trust my data to them.
Better get a "real" computer tape drive.

Problems with these video beasts:
- No read-after-write, therefore no decent error control.
- The additional conversion to an analog video signal means that the speed
is nothing to speak of.
- No filemarks, i.e. one backup per tape.
- How do you push the rewind/play/record buttons with the computer?
- Timing of the signal (usually, parallel-port) is likely to be rather
critical -> writing a Linux driver is difficult at best.

Sweeny's Law: The length of a progress report is inversly proportional to the
ammount of progress.
