I can’t offer any help with obtaining a film print but I’m very much interested as to why you feel the H.A.2 Blu-ray is poor quality. The only information I’ve been able to find so far are here: http://forum.blu-ray.com/showpost.php?p=12922453&postcount=69 and then very briefly, here: http://bluray.highdefdigest.com/2548/homealone2.html

Can you elaborate about the problems please?

What about the HDTV broadcasts? Are they an improvement or have they been sourced from the same master?
