Assuming videos of your dog / cat / children you're probably best storing
the original video files on hard-disk, burning as a DVD at standard
definitions (720x480 or 720x576) and enjoying the movies like that for the
meantime. I would revisit hi-def video disks in 5 years time, when more
tools are available, when you have a living-room player that will cope with
1920x1080 and when hi-def disks are cheap. You _may_ be able to record
blu-ray format onto DVD, but since you couldn't playback such a disk
yourself, why bother? Many viewers are unable to distinguish between DVD &
blu-ray.
Watch out for framerate issues - you should probably be capturing at the
correct framerate for your output format, as conversion between framerates
is problematic ("lossy").

I think that the most sensible advice :-)
I can convert current HD mp4's for storage a DVD:
mkisofs -o foobar.iso foobar.mpg4
cdrecord -v dev=/dev/dvd foobar.iso
though, I'll not be able to play them on any DVD.
For current usage I just convert them to standard DVD:
ffmpeg -i foobar.mpg4 -target ntsc-dvd foobar.mpg # convert to mpeg2
dvdauthor -t -o foobar foobar.mpg # author the file
dvdauthor -T -o foobar
