ok, then try this, download filmerit (link in sig) run it find the 2 codecs shown in the graph, unlock the padlock button to do a repair, and change the merit of the named filters to do not use. save and close, now see if it switches to xvid for dx50\mp4 files.
The only other choice you have is to use mkvmerge and change all you avi's to mkv's (takes 30 - 50 seconds per hour file).
I did this a little while ago and so far no problems, except PDVD will not play them but WMP11 does, along with MPC and VLC players.
