Just thinking back 10 years ago when I was arching all my DV tapes on my Dad's old G5... I did it all by hand through Final Cut Express. It would've been sooo much easier had I known about dvgrab back then!
For HD DV tapes there's also HDVSplit [2].

I've known for some time now not to trust media formats to remain easy to access as time goes on. Floppy disks, ZIP disks, SCSI…
So nice the home movies are now in the cloud (and on USB drives as additional backup).
