If it's just something simple to install or update, that'd be cool. I did manage to get one file (out of about 40 that I tried) to covert and transfer perfectly, so I'm a bit baffled why it will work occasionally. Especially when all the files are ripped with the same programs, are named in the same format and use the same ID3 tags. I installed a LAME codec years ago, so maybe I should just update it? But I thought that was for encoding, and to me this seems to be a problem of decoding and converting, although I don't really know a lot about this stuff. I didn't really buy the minidisc player for mp3s, so it's not a disaster, but I've got a stack of mp3 CDs that I use in my stereo, so it'd be good if I could play them on the MD.
