My iPod does not play my music
If your iPod does not play the music you synced with MGTEK dopisp, or it simply skips the song, there may be various reasons. Usually, this problem does not occur for music files ripped with Windows Media Player, but for music files obtained from an unknown source.
You synced a corrupted music file
MP3 music files downloaded from the Internet are often corrupted, i.e. they do not comply with the MP3 specification. If the music file is corrupted, the iPod may skip the song or behave erratically. The fact that you may be able to play the music file in Windows Media Player does not indicate that the music file is OK, because Windows Media Player is more fault-tolerant than your iPod.
To verify that the music file is indeed corrupted, you can try to sync the music file in question with iTunes. If the music file is an MP3 file, you can also try MP3VAL to validate and potentially fix the MP3 file. MP3VAL can be downloaded at SourceForge.
You synced a music file with an unsupported encoding or bitrate
An iPod cannot play all music files you may be able to play with Windows Media Player. If you sync music files and Windows Media Player fails to determine that the music file needs to be converted, your iPod may skip the song. For a list of supported file types and formats, see the iPod Technical Specifications.
