I use AeroPlayer on a Tapwave Zodiac (a Palm PDA) to listen to music. I downloaded a song from a CD using Windows Media Player, and it ended up in my Library as a .wmp file. I installed NCH Converter and converted the file to an mp3, and installed it, but although the title appears in the Zodiac native music player, it won't play. It doesn't even appear in AeroPlayer, my preferred player! It's in the right MIDI file on my card. The bitrate is set at 128 on the converter. Is there something else I have to do to get it to play play on my Zodiac? Is there a way of ripping it as an mp3 in the first place?
