Just got an opportunity to try it tonight, and here is exactly what I do: I start-up DVDfab HD 3.1.2.8Beta, set the quality to "Blu-ray" and "Full Disc" is the default DVD to DVD option. I insert the BD (BBC's Planet Earth, for example) and the quality setting changes from Blu-ray to HD-DVD, then to DV9. DV9 remains the only quality option--I can't just reselect Blu-ray.

I'm wondering now if it may have to do with something having been omitted from the XP install: I slip-streamed and tweaked the installation, using n-lite, to a pretty barebones install of XP Home. Fortunately it's not yet activated and I can try a complete re-install if that would be a concensus recommendation.

Thanks.
