MP3 DVD

[RacerXRed]

I recently bought a Alpine dvd/mp3 car stereo headunit. It can play cd's with mp3's on it just fine. I thought it would be nice to have a dvd full of mp3's figuring I could get 30+ cd's worth on there at 320k/bitrate. I wasted 5 dvd's trying to get this to work. I tried everything from just creating a data dvd and dropping folders in the structure, changing the book-type setting from dvd-rom to dvd+r, and using Nero's mp3-dvd program. The only thing that worked is changing the book-type, only problem is the unit won't play beyond a certain number of folders. Any suggestions for this? Below is from the manual:

• Discs that cannot be played
DVD-ROMs, DVD-R/DVD-RAMs, DVD-RWs, DVD +
RWs, CD-ROMs (excluding MP3 files), photo CDs, etc.

· Use discs with MP3 files written in the format compliant with
ISO 9660 level 1 or level 2.

· Corresponding File Systems
This device supports discs formatted with ISO9660 Level
1 or Level 2.
Under the ISO9660 standard,
there are some restrictions to remember.
The maximum nested folder depth is 8 (including the
root directory). File/folder names are limited to 31
characters (including the extension).
Valid characters for folder/file names are letters A-Z (all
caps), numbers 0-9, and ‘_’ (underscore).
This device also can play back discs in Joliet, and other
standards that conform to ISO9660. However,
sometimes the file names, folder names, etc. are not
displayed correctly.

It says clearly that the only DVDs it will read are +R, so there is no real surprise that that is the only one that worked.

Most players do have a limit to the number of files it can see, regardless of structures used. My DVD player has a hard limit according to the manual. Can't remember exactly how many, as I don't like the sound of MP3, and the better the system, the worse they sound. I suspect you have found your limit.

Many manufacturers now publish the manuals on the net. Might worth seeing if there is an updated version for yours which has more detail.
