Here is the ever message : MP3 files with a non-44.1KHz audio sampling rate will be transferred. Please note that some devices or medias cannot support playback for files of this type. If you cannot play these files with a device, change the transfer settings to Specified bit rate transfer mode. Here is the information for the MP3 in question : Size: 10537710 bytes Header found at: 1040 bytes Length: 2634 seconds MPEG-2 layer 3 32kbit, approx. 101314 frames 22050Hz Mono CRCs: Yes, Copyrighted: No Original: No, Emphasis: None And here is the info an MP3 that works : Size: 10429041 bytes Header found at: 1040 bytes Length: 2607 seconds MPEG-1 layer 3 32kbit, approx. 100269 frames 44100Hz Mono CRCs: Yes, Copyrighted: No Original: No, Emphasis: None Can someone convert that error message into something that I can understand? I'm interested to find out why it occurs and why I have to convert to ATRAC format to get it to work. Thanks !
