Yes,

VCD, SVCD and miniDVD should play in most standalone DVD players. Also DivX and XviD videos may play in some standalone players (read your player's manual to find out).

All these formats use CDs as media and not DVDs. However in the 3 first (VCD, SVCD and miniDVD) you need more than 1 CD for one movie (usually 2 or 3). DivX and XviD can fit in one CD with nice quality, but not many players support them.
