Hello, I am newbie here. I have 08 X5

Just wondering if I could play music files burned in DVD-RW in 6 DVD changer in globe box. I am pretty sure I can play music files burned in CD-RW, but not sure about DVD-RW.
Comparing 700MB for CD and 4GB for DVD makes huge difference, since I don't have usb port or streaming bluetooth with 6 DVD changer and CCC iDrive.

Is anyone have better way to play music in earlier e70?

Thanks,
