well i'll certainly try it again if it makes you happy Baggy and i didn't mean to cause offence.. but for now i stand by my findings posted here in this very thread last Summer (its fake shit!)

i'm not anti-upmix at all but an upmix can never be rightly described as discrete, as good as they get they're just not and its a bitter pill to swallow at times because there are some really great upmixes out there and in many cases its all we have in Surround (such as this Robert Plant DVD, poor as it is) but there'll always be some degree of compromise with bleed, artefacting, etc.
tbh i wish they had just done this DVD in Stereo. speaking of which, did you try the Stereo on this thru something like PLII Music? i haven't yet but i'll bet you get as good results as the DTS 5.1 on the disc, maybe even better!? something to fiddle about with on the long Winter nights methinks!
