DC MP3 Biterate help please!!!!!!!

[mattyj]

Can anyone please tell me what bitrate the mp3's
have to be to play in the dreamcast mp3 player!
I got the image from dc copy world and burnt it
to disk with about 10 mp3's but only 4 of the tracks worked?
I have heard this is to do with the bitrate but what bitrate do they have to be?
I think it must be 192000 because 3 of the tracks
that worked are that rate but i'm not sure and I dont want to add another coaster to my pile,
so help me please!!!!!!!!!!!!!!!!
