Dear Richard,

1. there are sebveral tool that allow you to record in different video codices,
incl. mpeg2. We (www.spomedial.org) use the Ulead DVD Power Tools.

2. Do you like to use it for datastorage or for video storage?
Data storage from what I know, is not possible (and it would take a long time
to find the right datapoint, as it is a tape) - but of course you could send
videos from hard disk via firewire etc. back to tape (as videos mostly are the
only big files on a hard disk, this makes sense).

sincerely, stefan
