Actually, whatever you'd thought of as mentioned in your reply, we had
thought of that too, and set up the appropriate h/w and encoder profile.

We used a quad-core CPU with 2GB memory, a 26" monitor in resolution
1920x1080 (probably higher). For WM profile: use WMV9 codec, 1920x1080,
30Mbps, 100% quality level.

Run in WME directly. The preview picture shown in 100% size without any
slow-down. But the picture doesn't show any HD-quality, nor the encoded video.

I then read the documentation for the WM profile; the top resolution
mentioned seemd to be just 768x576. But then the documentation was dated back
to year 2002 (and haven't changed since then ???) so I presumed WME wasn't
prepared for HD-encoding at that time.

You can't do realtime (live) HD without setting the quality to 0 or close
to it, even on a quad-core. If you want Blu-ray quality then you must
capture uncompressed or lightly compressed (low-cpu) and then 2-pass encode
after the fact.
