Gene,
HDV does a pretty good job of it on a minDV tape, and 80 minute tapes for
HDV are on the market now. Not sure if you can pump HDMI video into an HDV
camcorder and have it record in HDV. If so, then capturing HD via the HDMI
port using the Blackmagic and then copying it to a miniDV with a camcorder
would be a sweet little archiving solution at relatively low cost. Nice to
see the Blackmagic has both HDMI IN and HDMI OUT ports. :-)
