Help: songs skip on my iPod touch 2

Question

First, I'm sure it's just the problem of the iPod touch, not the audio files, because they all play normally not only on the iTunes software, but also on my iPod nano 3 as well.
So here's the exact problem:
For all my audio files compressed by Nero AAC codec, the last few seconds, bar none, will be skipped when played on my iPod touch 2.
However, there seems to be a fixed pattern for such skipping: if the song's length is 1 minute, the last 1 second will be skipped; if it's a 2-minute-long song, then the last 2 seconds will be skipped, then you can do the math yourself.
I'm not sure about the exact seconds, but that's the way it works.
Since most songs will leave a few seconds of "space" in the end, such skips are usually harmless. But for a continuouse work that's divided into several tracks, or some concert work that weighs as much as 20~30 minutes (which means the last 20~30 seconds will be omitted), your enjoyment can be severely impaired.
Here's something else worth mentioning: all the mp3 files compressed by lame or iTunes, and AAC songs bought from iTunes Store have no such problem on my iPod touch, which only affects AAC files encoded by Nero AAC codec, CBR & VBR alike.
My iPod touch's software version is 2.2.1 (they don't fix the problem since 2.1, when I bought the iPod)
Is there a way to fix the problem, or at least, will somebody tell me that I'm not alone on this?
Thank you!

Have you tried converting them using iTunes itself? If you want to keep them as AAC files, first, open iTunes Preferences and then open Import Options. Select AAC from the drop down menu and select OK. Then, select the tracks you want to convert, right click and select "convert to AAC". Once they've converted, delete the original files then sync the new tracks to your iPod. If the skipping continues, maybe do what I said above but convert them to MP3 instead.
Hopefully it's just an encoding issue, and that re-encoding will solve it.
