Ok Elmo here's some tips, I doubt VP will be restricted to iPod limitations. Since 1500kbps at 640x480 would be appauling on most videos.
As for the low bitrate I think when we do encode in XviD we'll would stay as far away from VCD as possible.
And judging your source looks American, and when deinterlaced can look terrible without heaps and heaps of filters.
To make a good sample should something live (since they have heaps of motion and generally are better quality)
And filmed by the station or from country with the same Video Format eg. NTSC or PAL who cares about res.
Frame Rate differences and interlace is where most quality can be lost.
And most editing in megui can lose you some quality if you don't know what you're doing.
Anyway I made an Watermarked XviD sample.
It's of an upcoming VP release (The Kooks - Naive (Abbey Road))
I capture generally MPEG-2 about DVD quality since my drivers have a problem with lossless .avi capture most of the time.
The source was the channel MAX (720x576i 16:9 25fps)
The actual show Abbey Road is shot in HD but scaled down to 720x576 but it's progressive since it's only 25fps, Not 50fields.
Since it's progressive no Deinterlace is needed, so it's already good quality

To encode I set up an avisynth script in megui and made my own alterations.
Mainly to add the Donald Graft Logo VirtualDub Filter.
It's manual in avisynth but can be previewed when the .avs script is opened in VirtualDub
I encoded in XviD using A Quantizer encode, Had it set to Quantizer 2 so very little quality loss. The Final bitrate was >3000kbps and looks great.
Audio was just a basic Lame MP3 encode and set to 192kbps.
The Script is used to encode the video looks something like this:
