Steve,
I’ve been waiting for a recordable format to do the same thing you want to do with home videos for a few years now.
I was never happy with the quality loss when compressing the raw miniDV video to DVD+R and gave up after trying to find a way to burn them to DVD+R-DL.
I would love to back up my home videos to recordable blu-ray now that it is affordable without having to use any compression.
Have you had any luck and if so can you advise me of what you did?
Thanks in advance.
