DVD MP3 playback vs. CD MP3 playback on Samsung S221

[bonusbuy2]

Most of the DVD players are capable of playing CDs containing MP3 files. However, when I tried to burn MP3s onto a DVD, the player (Samsung S221) was unable to play it back. In other words, it appears that there should be no difference if the files are on CD or DVD. Yet, this seems to be the problem. My questions are:
1) Has anyone tried to play-back MP3s from a DVD?
2) Is this issue related to the DVD-Player hardware?
3) If is is possible to play back MP3s from DVD, how should they be burned?

if you check under the dvd players section you can search for dvd players that play dvd-mp3 discs, i personally dont own one that can, but it will be a option i want on a new dvd player. also im not sure if there would be any special way to burn them, probably just as data
