Unreliable Seek Position

I am playing back a mp3, charting out it's waveform, making markers on the waveform, and using those markers to seek to those sections of the playback. The player is set to auto start, and if I seek to a position while the player is relatively early in the playback, it seeks just fine. The farther I let the playback continue the more incorrect the audio in the playback is.

Example on a 30 second file:
Current time is 0
Seek to 18 seconds, both audio and time are correct
Play to 25 seconds
Seek to 18 seconds, the audio is actually around 14 seconds, but the time displayed is correct

Changing the bitrate to 16bit instead of variable fixed the issue.

This may be relevant. Audacity, VLC, etc, all say the file I am using is 24 seconds. Jwplayer thinks it's 37+ seconds.

{position: 18.37, duration: 37.512, type: "time"}
