As a user of xmpeg to encode movies i've made the discovery that bilinear resize looks sharper than bicubic.

:) yeah i do agree most of the time i get a sharper picture with bicubic.let me refrase it how do i get a clear picture as near the original dvd picture :) swedish hobbit

Yes bicubic gives sharper results but it could results in more block. Bilinear will give you a smoother picture but it removes some details and it it could also introduce more aliasing
