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

MP4 or AVI files will definitely work but make sure your USB memory is formatted in FAT32.

change your burn software and file formats /if there are music files/

If you are trying to play music, then there could be only two problems.
1. Some DVD-RW can unintentionally trick you into thinking that they can play music, if inserted into the right machine. But really what it might really mean is that it can transport music, not play it.
2. The format of the file that you burned onto the disc may not be compatible with the type of DVD-RW that you have.

If you are trying to put an actually DVD/Movie onto the disc, then it is more than likely a format problem. I imagine that it may be really hard to get a video into the correct format so that it can be played on a DVD-RW.
I assume that whatever you are putting onto the DVD-RW is completely original. If it is not (such as a movie you got offline) then copyright laws will take all happiness out of your life.

You can burn the mp3 music files to a DVD disc. Just burn the mp2 files as normal data files.
Some CD players can play mp3 music files but they need to be burnt onto a CD disc NOT a DVD disc.

When you burn the videos to a cd or dvd disc make sure it is in one of these formats: Video CD (VCD), DVD, SVCD because thats what video formats that HU plays

what parts? whats is not working?

If you are burning a "Data Disc" (the burning software should tell you or have you select it) then music will NOT work on a CD-player. It will only work in another PC.

Data disc is for files, pictures, videos, music that you want other COMPUTERS to be able to read and play.

If you want a music CD to work in a car or something like that it NEEDS to be burned as a music disc, not data.

Hope that helps.

im assuming you have a dvd player in your car as opposed to a regular cd player

you need to look in the manual of your car stereo and see what kind of discs it can read... there are dvd+r, dvd-r, dvd-wr, dvd-ram, dvd-r (dual layer), etc, etc....

make sure your using the correct format disc and also make sure when you burn the music that your burning them in a file format compatible with your stereo (wmv, mp3, etc) check the manual

i had the same problem with mine i just kept hitting the reset untill it stopped.

What kind of recordable discs are you using
