Does anyone know what are the standards for making MP3 CDs that would play in MP3 compatible CD and DVD Players? (I'm probably going to be using them on a DVD player).
First of all, what is the folder structure of MP3 CDs? Do I just burn a CD with a bunch of MP3s on it, or do they have to be in some folder like AUDIO_TS or VIDEO_TS folders on DVDs?
Secondly, what format do the MP3s have to be in to play on compatible CD and DVD players?
MP3 or MP3 Pro? 128 or 192 or something else? 44Khz or 48 or other? What else?

Thanks for any help in advance.

Since the general tendancy is for people to make their own MP3 disks, rather than purchase manufactured ones, I would think that a player would have to document what it can handle, so that people can meet its expectations. There is probably nothing even remotely like the orange book specs for MP3 CDRs, so every model player might have different requirements.

My DVD player needs all mp3 files to be in the root directory, my car player handles directories, playing all files in one directory, then going on to the next. I prefer the latter - it's obviously better for organising the files & provides a quick way to scroll through directories, then through files within the directory. The directories can be named however you like.

Ok, so the folder structure can vary. But what about the mp3 formatting, what bit rate does it have to be and how many Khz?

I have several devices which read and play MP3s burned to CD-R.
I have three portable Discman type devices - a Samsung, a Philips and a Rio Volt and two Panasonic DVD-Audio players which will read and play CDs and MP3 CDs (obviously also a number of PCs). All of these handle directory structures in the way Alan says his car player does. They also handle any bit rate of MP3 I have yet thrown at them from somewhere around 40kHz up to 320kHz. They just seem to adapt to whatever is there in much the same way as Winamp does on a PC.

In my experience you should make sure that you use a 44.1kHz sample rate and encode with a constant bit rate rather than a variable bit rate.

Cheers.
