Same here, is there really no documentation available anywhere? I've mailed the Ahead folks some time ago about other stuff but I've never gotten any reply. Maybe if enough ppl try and mail them about the .nri format? Of course we could reverse engineer it but that's way over my head, how about yours?
One more thing: instead of converting the m3u to nri, how about burning the m3u straight from Winamp using the API as a plugin? You'd still need the format info since it's not an easy we're burning, right?
