I then copied the DVDs to my NAS for safe keeping.  But they are hard to work with in that DVD format. lots of .VOB files and DVD menu files, etc.  If I could convert these to mp4 (h.264) files they would be better for storing online in a safe place.

I have a note of this: ISTR that I've used it in the past.


Extract the 4th track from a dvd .iso image

mplayer -dumpstream dvdnav://4 -nocache -dvd-device infile.iso -dumpfile
