.ts --> XviD/WM9 encoding speed?

[The Belgain]

What kind of speeds are people getting for doing this conversion? My source is a 1280x720p 60fps captured .ts file (from MyHD i think). I'm converting to 1280x720p 24fps (it's a movie).

My Avisynth script is this:

LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\MPEG2Dec3dg.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\Decomb.dll")
mpeg2source("D:\DVD\HD\test.d2v")
SelectEven()
Decimate(cycle=5)


I'm encoding using VDubMod with XviD 1.0 RC4, and with WM9 VCM. With XviD, I get about 3-4 fps for both passes. With WM9 I get about 3-4 for the first pass, and 2-3 for the second. My machine is a Barton 3200+. This seems very slow; what speeds are other people getting? The quality in WM9 is set to second-highest, and I'm using "understricted" profile, with mpeg quant in XviD. Target bitrate is quite low (3.5 MBit) as this is just for testing. Using 2pass for both.

What XviD settings do people recommend for HD. I don't care that much about decoding, because these boht decode very easily on my machine.
