If the files are originally M4P, they're already lossy. Re-encoding them into another lossy format like M4A or MP3 will only serve to lose even more audio data.
Best to stop the losses at this point and use a lossless format, since you have the choice. If it doesn't bother you to lose even more audio, then just encode in what sounds the best to you at a given bitrate OR what sounds the same at a lower bitrate. Apple AAC and Ogg seem to have more efficient coding methods and can achieve the same sound quality at a lower bitrate or better sound quality at the same bitrate. Just be aware that when you use different encoding models (for example, going from AAC - MP3) you will get artifacts of both, so M4P - MP3 will probably sound worse than M4P - M4A and will also sound worse than original WAV - MP3, where you're only using one encoding model. -- Mark Lanctot 'Sean Adams' Response-O-Matic checklist, patent pending!'
