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
