Took me a while to find this for you. Was sure that I had seen it on this site somewhere. An external link is mentioned in comments to Tadad1 upload of version 2 in the tools section. Here is the link to AVIConverter V3:

V3 seems to use the same components as V2 but with a modified convert.ini file for screen size 320x240. If your screen size is 224x176 then you should use V2 or modify the convert.ini in V3 appropriately.
The convert.ini can be easily modified to change frame rate, video and audio bitrates. You can create a number of different settings that are appropriate for your uses depending on the videos you're encoding and your player's performance.
