dvd player question

my norcent dp300 home dvd player says its compatible with dvd,cd,cd-r,cd-rw and mp3.And i know for a fact
that it is region free now.

when the manual says dvd, dose that mean in can play
any type of dvd media such as dvd+rw,dvd-rw,dvd-r
dvd+r or it means you can only play orignal dvd's?

cause the funny thing is i download a divx movie and
demux files, then used tmpgenc to convert to vcd(mpeg1) standard then multiplexed using ifoedit then
burned it with nero and all seems fine for vcd which was recorded on a plain cd-r.that proves that yes my norcent home player can play burnt cd-r's.But the same does not hold true for dvd+rw?
