I'll look at that site.
I tried using WME9 on an Xvid file and it seemed to work ok - 70%-80% CPU on the first pass, 95%-100% on the second - with good total encoding time. But before that I uninstalled/reinstalled codecs so I really don't know what caused the change, but codecs are always under suspicion.
Thanks for your help. While I haven't posted much, I've learned a lot over the years by reading the forums here.
