first is the format of the video needs to be mpeg2 not avi, you can eihter convert to it or you can re-record in it. secondly there is dvd+r and dvd-r as well as dvd+rw and dvd-rw. though even if you can burn all those formats there is no garuntee that the dvd player that some other family member has will be able to play any of them - which could happen with older dvd players as well as really crappy ones...
