Converting from Quicktime/Midi audio files to MP3 format

Before I upgraded to Tiger, I could use itunes to convert into mp3 form all the Quicktime Midi files that my chorus director emailed to me. Then I burned them on to cds so that everybody in the chorus could play their part in their car on the way to work and learn it really well.

Well, now when I go through the exact same steps that are on the website (go to preferences, go to advanced, change encoder to mp3, etc etc) and itunes says that it cannot convert the file to mp3 because of "unknown error (-50)."

Any ideas on how to get around this other than trashing my Tiger and going back to Panther?

I bought and downloaded quicktime Pro and used it to convert my MIDI files. First you have to find your MIDI file on your HD. Then drag it into QuickTime. Then "export" the file and in the export window select aiff as the format. Save it to your HD. Then drag the aiff file into iTunes and it will play in iTunes (6.0.4 is the version I'm using) It will also burn to a CD from within iTunes. If you only want to play the file from within iTunes, you can skip the QuickTime conversion, and simply drag and drop the MIDI file from your HD into iTunes - iTunes will play it but won't allow the file to be burnt to a CD.

I need to make cds that can be played on any machine, so that doesn't help.

I also do not have Quicktime Pro, so I now have to open the midi file in Garage Band, and under "share" I send it to iTunes. In iTunes, I convert the AIFF file to an mp3 and burn it to a cd and it can be played on any cd. I guess I'm stuck with that extra step, but it's better than nothing.
