If the videos are multiplexed MPEG files then the audio and the video are muxed onto the same track. QuickTime, and therefore any application that uses QT like iTunes, the iPod, iMovie (Mac app), etc. expect two separate tracks, one video and one audio. So when you convert these muxed files, the video is played and the audio is not heard.
iPod plays video but not audio of some exported files

So you need to do a conversion on the file first. MPEG Streamclip is a popular one that comes in both Mac and Windows versions and is known to "repair" this problem.
There are other applications that can do this as well. Try searching the iLounge.com web site for more conversion help. But your root cause is the muxed MPEG files.

AAC is an audio format not video. When you used iTunes to convert your videos, iTunes convertedm the video to MP4 format. I had this same problem too. No sound. Try 3rd party softwares to convert your videos to MP4. I use ImTOO 3GP Video COnverter. It can convert videos to various formats - same goes for audio.

Once converted, add the converted file to your iTunes library and from there add it to your iPod.
