There are no codes to install. Go to guides and search for "Ipod".
Here's what I have:
Open Recode2
Click "Recode Video Files To Nero Digital" (4th option)
Click Import Files on the right
Go down the list and select file (where you saved the mpeg/mpg file)
Click add file
Click More at bottom left
In drop-down box to bottom right "nero digital profile" select portable (meaning ipod)
Unselect Fit to target
Click next
BURN
--------
Click Nero Digital Settings to the left
Then check the box Expert Mode
Encode method "High quality encoding - 2 pass
Quality/Speed, select Extra quality in performance/quality box
Advanced, check simple profile box
Click burn.

Depending version of Recode, menu/boxes will differ.
I tried above on Recode2, was able to burn "Madagascar", Music video etc.
Give this a try or send me your email address I can send the guide what I found from afterdawn.com.
