Format factory settings for Kenwood car stereo videos

[Drew200]

Hi all, I'm hoping someone can help me get the right settings for format factory.
I'm trying to convert movies to play in the car.
The car unit is a Kenwood DNX4150DAB.
I've gone through all the books, all the web content I can find, and tried many different conversions, I am close but its not right.
I am playing everything from a usb connection, music works fine, everything else works fine just videos have a problem.
To begin with it would play videos fine but with no sound, so after a lot of mucking around I got it to play both video and sound but there's still black lines down each side of the movies, the most success Ive had is by doing this, open format factory, click mpeg, add movie to be converted, click output setting, choose VCD PAL,
change video size to 720x480
change video bitrate to 6000,
change FPS to 29.97,
change aspect ratio to fully expand, or 4.3/16.9

If I change the audio sample rate from 44100 and the bit rate from 224, I seem to lose sound altogether, though I have only tried 48000 and 448 as they were default with other presets.

Here are the specs for the player, any help with the correct video size, bit rate's, fps and aspects would be greatly appreciated as I've spent so long trying to get it right.
