DIVX licensed => XVID free (also for RTD1296)
Some may have the wish to play old DIVX (AVI) videos. These are not supported due the licenses involved with those. This is valid also for previous generations players as none support DIVX. You can bypass this limitation using this simple program:

Set it to change the DIVX header into a XVID header and all done. Available for MAC, Windows and Linux OS versions. Bulk conversions are supported.
But it does not make all AVI's play so there must be something else not being supported.
Suggested by others is also to use mpeg4modifier. It identifies some files as packed, tick the box to unpack and save.
