iPod mini scrubbing issues with low bitrate MP3s

When I try scrubbing through lower quality MP3s on my iPod Mini (2nd generation), the indicated time and actual position in the song are desynched. If I scrub too far, then the iPod will just skip to the next track. I am on the newest software version (1.4.1), and all the songs have been loaded on through iTunes. No other MP3s (or songs in other formats) do this, is there any way to fix this?
