Hi Matt,

If you intend to archive the material I would definitely not simply
'dump' to DVD. That's OK for viewing copies but for the longer term
DVDs are not very robust or reliable and MPEG-2 compression is lossy
and dogged by artefacts. Better to store the material on hard drive
(or hard drives, keeping clones as back ups on other drives). A good
video standard would be DV-PAL QuickTime (or DV-NTSC if you're in the
USA) - non-Mac folks will be able to advise about AVI files, etc. It
sounds like you have about 50 hours of material, with DV files at
around 13 Gb per hour you would need 650Gb for all the material, so a
pair of Terabite hard drives should be enough. Make sure you turn
the drives on at least once a month to stop them seizing up. It
would be a very good idea to also make tape copies to a good archival
format like Digibeta.
