WinDVD Aspect Ratio Problem

[Booms]

When converting an avi file to DVD using WinDVD the final result has altered the aspect ratio. I have read a help message posted by setarip back in November about using VirtualDub to rectify this but I get stuck on Step 4 where he says
"4) Put a checkmark in the box labelled "Expand frame and letterbox image - and enter a multiple of 16 in "Frame height" (Perhaps 208, or 192 to approximate 16:9 - which, in this example, will increase the height from 480 to 688 or 672)"

The original avi file is 640x352, I would be grateful for any help anyone could give me on this,
Many thanks.

"4) Put a checkmark in the box labelled 'Expand frame and letterbox image - and enter a multiple of 16 in 'Frame height' (Perhaps 208, or 192 to approximate 16:9 - which, in this example, will increase the height from 480 to 688 or 672)'"

In the above example, you would enter 688 or 672 as "Frame Height"

And then:

5) Click on "OK" to return to the "Filters" window

6) Once again, doubleclick on the "Resize" filter
7) Set "New height" to 480 (This will reduce the ENTIRE image, including the black bars to 480 pixels of vertical resolution). Click on "OK" until you get back to the main VirtualDub window
8) Save with a new filename
