Does cyberhome ch-dvd 300 dvd player play burned mp4 movies?

Regular standalone DVD players can only read movie DVD's (those are in MPEG-2, and if you view them in Windows Explorer, you see a folder structure with VIDEO_TS, and files like .VOB .IFO and .BUP). Newer DVD players that are DivX-certified can (in addition to the above) read data DVD's with an AVI file encoded in the DivX codec. Most of the time, you will fail to play MP4 on DVD player unless the DVD players have the "Nero Digital" label on them.

In order to burn MP4 to DVD for successfully playing on various DVD players, we had better find a powerful MP4 to DVD burner which will automatically convert MP4 to DVD player compatible format as well as burn the converted MP4 files to DVD disc.
