Patrick,

My understanding was the same as yours, I have to admit.

Like you, however, I'm not entirely rooted in the MS world. Hence my
question about whether anyone had experience to show whether the
DVD-encoders would take advantage of multiple CPUs.

I'm familiar with the argument that, even if they don't, there will still
be some benefit, as the O/S uses a different, less busy CPU, to do its
housekeeping, so you can actually get 100% utilisation by your chosen task,
but it would be even better if the encoder COULD spread its load.

Paul
Are you sure that multi-threaded apps are distributed across 
processors by thread? My understanding is that it is _processes_, not 
_threads_, that are distributed across processors in a multi-
processor environment, but then again, given your intimate knowledge 
of the MS world I could be on dodgy ground!
