Your biggest issue is getting the data from the tape to a digital file. I don’t recommend DV since it is more compressed than DigiBeta (5:1 versus 2:1), although it depends on the needs of your client.
If you could get it transfered to a Quicktime file with the MJPEG format (quality of 95%) you would get reduce the file size about 2/3 over uncompressed, and (in my opinion) it looks pretty good … much better than DV.
Good Luck,
