If you have an MP3 file that was purchased from Amazon.com, iTunes, or another online music store, and it will play in other music players but not in MediaShout, the file itself may be at fault. If some MP3 files will play in MediaShout, but some purchased downloads will not, the file may be improperly encoded.
We have identified an issue occurring with some MP3 files that have been purchased from online download services which involves a subtle corruption of the file structure that most music players happily ignore. These files do not meet the technical specifications of the MP3 file format. Unfortunately, the Windows DirectX process that MediaShout v4 uses is VERY particular about the validity of the file structure that it is asked to play, and it will not play these files. The problem is caused by the software that was initially used to create the file by the download service, and there is no way to repair the file that we know of other than to burn the MP3 file to an audio CD and then rip the resulting audio CD. This completely re-encodes the file and corrects this issue. Instructions to do this are listed in this article.
Note: We have notified Amazon.com technical support of this issue, and due to the fact that they only officially support Windows Media Player and iTunes for playback, if a file plays in those two players they don't care if the file structure is incorrect and are unwilling to change the files. While it's doubtful that it would make a lot of difference, complaints from dissatisfied customers who've experienced this issue might possibly encourage them to change their position.
