Convert MP3s to a lower bitrate
If you have ripped your CDs using a high-bitrate MP3 format, such as 256k or higher, you may want to convert the MP3 to a lower bitrate before you sync the MP3 to the iPod in order to save space on your iPod. You can configure MGTEK dopisp to convert high-bitrate MP3 files for you automatically. The conversion is performed as needed during sync, and does not affect your music library.
Note Do not select a maximum quality level in the iPod properties dialog. This option is for native MTP devices, and will conflict with your iPod device.
