I listen to audio books or lectures and the progress bar always reaches the end before the file is done. What's wrong?

Article applies to both the Palm and Windows Mobile operating systems

 Most likely this issue is caused by files being recorded with a VBR (variable bitrate) that do not include the xing tag in the file header. Some encoding software programs do not include xing tags. When you play a long VBR files, Pocket Tunes has to "guess" as to the length (time) of the file, and most often that guess is wrong unless xing tags are present. To guess accurately we would have to scan the entire file which would take an unacceptable amount of time for most users.

This situation should be easily resolved by re-encoding the files at a set bitrate, or if you are comfortable editing tags, add and enable the xing tags in the files. The easiest method would be to re-encode at a static bitrate, obviously.

A Pocket Tunes user reports he successfully used the vbrfixwin program to add this information to his VBR files, and it has solved the problem. You can download vbrfixwin from

NOTE: We suggest you first experiment with copies of your original files, just in case something goes wrong.

Should this somehow not resolve the issue, you may send us one of the files for testing if you would like to do so.
