I have burnt mp3s onto CDRs and played them fine on my new DVD player, also I've burnt films fine. I tried using one of the ISO disk project modes, or something, to make a compilation of MP3s on a DVD, but my DVD wouldn't accept that. So, I assumed I may be able to create a DVD Video project and simply put all my mp3 folders into the Audio folder of the DVD. However, the burn icon is shaded and it won;t let me burn the complilation like that. Is there something you need to do to make this work, such as encoding the mp3s whatever that means, or do I need to use a specific project type which I haven't tried? I'm not sure exactly which project type I tried which didn't work originally on my player, but there are quite a few and I'm not sure which is which. I've made a big project and I don't really want to have to scrap it if I don't have to as I edited each folder within Nero rather than outside of it.
