Zillions of mp3s on DVD,but it don't play!

[Peter McL]

I've tried copying mp3s onto blank DVDs, (using Nero 6), as I have stacks of mp3s on my hard drive and DVD+Rs have so much storage capacity. The idea is to play back through my Phillips DVD R75, which is linked to my setero system. Copying mp3s to CD-R works OK (though the DVD R75 has a habit of 'skipping' some of the tracks for no apparent reason,) but when I copy onto DVD+RW, the disk will only play on the computer. When I insert it into the DVD R75, message comes up 'Data on disk cannot be recognised'. Anyone got any ideas how to fix, or what I might be doing wrong?

Thanks

Peter
