Xvid HD to xvid (lower resolution)

[Danti]

I'd like to resize an xvid hd 1080p to a lower resolution xvid so that i can play it on a standalone player. This is the avisynth script that i have been using

=========================
DirectShowSource("",audio=true)
BicubicResize(960,544)
=========================

Target bitrate is around 1200kbps

The result seems to be very blocky. Shall i lower the resolution even further?

What standalone device are you referring to?
I believe a great majority of dvd/divx players don't support resolutions higher than 720.
My dvd/divx player certainly doesn't.
