Help! a 16:9 Source DVD disc was encoded differently in DVDx

[silab]

OK, so i chose on

Zoom (Pan Scan 4/3)
Resize Filter (MMX Bilinear)

Then get tmpgenc to encode it by using cyberimage's template.

But the result file is weird, it cuts off the sides which shows in the original dvds.

Which setting did i do wrong? Should have I used
Full 16/9 or 4/3 input in Zoom?

Thanks
