Playing DVD mp4 files

I hope this isn’t a stupid question (if so, try not to be too cruel)…

I burned some DVDs with a large number of short mp4 and mov files downloaded from the net. I wanted to just play them individually or back-to-back in my standalone DVD player the way I play mp3 audio files. Problem is my player only sees two or three files on each disc (my G5 will read all the files).

My question is, do I have to author a DVD to read these files, or is this a shortcoming of my particular player (Cyberhome CH-DVD 320). Let me know if I need to provide more info. Also, if this has already been covered can someone direct me to the thread; I haven’t found this topic yet.
