My sister says there's a hold button that must be slid & this will release your mp3 player from being "frozen" Good luck!

SOURCE: My dual xdvd700 wont play cd-r discs with music videos on them.

dual xdvd700 is a very picky device in order for you to play videos on a cd-r disc...you need need a burning software that have video burning capacity...don't just burn video as data copy/backup b/c dvd player won't recognize it. hope this help...
So it's base on how you burn your disc...NO data backup/copy ...use Video Burning instead

Check the stereo's specs: 4 gb might be too much. It's possible they could limit you to 1 or 2 gb max. Many JVC stereos limit you to 2 gb, this one might, too.
