No way to listen amr file on Nokia 3650, I always get an error from Real Player. I tried different conversion (Nokia Multimedia Converter 2.0, Ericsson AMR converten, Totonox AMR Converter). File is correctly reproduced on my PC and on my 7650 (with Nokia recorder), but no way for Nokia 3650 (RealPlayer reads the file and can't reproduce it).
Any idea? Is Real Player fully compatible with AMR? How can I avoid RealPlayer starting (ex.: using audio/mp4 or other mime type)?
