Hi Jim,

Thanks, but the whole point of the project is to get away from tape.  Away from expensive hard to find drives, alignment and tracking problems, tape tangles, obsolete data interfaces, maintenance issues, non instant random access, etc.  I even have a scsi mini dv tape drive (if i can find it) I'll sell for $100 if anyone wants it.  That's not a direction I'm interested in going in.

Sincerely,

Ron
