Heya Dave!
Ripping the DVD and converting the video VB file to a DV stream
via Quicktime did not work. I could drag it to iMovie. but all I got
was the video -- no audio.
I then stumbled across
this website.
I simply downloaded the free streamclip software and paid $19
for the MPEG-2 Apple license and away I went.
I opened the same VOB file with streamclip and converted it
to DV. I then dragged it into iMovie and voila! It worked!
Not sure why I had to pay $19 for the MPEG-2 playback license.
Not sure if that affected anything or not as I didn't use Quicktime
with this process.
