A very, very late post to this thread, but I just started looking seriously for a DVD collection program. While looking at Movie Collector, and also reading about all of the angst among users over their sudden change in upgrade policy. Despite the upgrade thing, it does appear that many DCers are still using MC and speaking well of the program itself - if not the developers.
One disavantage: No discount here at DC.

So I decided to look around for one elsewhere, and lo and behold: There is an $8.00 discount for users of ListPro by Iliumsoft. I have used ListPro on a Pocket PC and desktop PC for years and never new about it. The page, hidden away on the collectorz.com site - the only way I found it was through a link on the Iliumsoft web site - is here:
http://www.collectorz.com/listpro_offer.phpAnd the referring page at Iliumsoft is here on their support site:

I was using DVD Attache, a free app from a private developer which is very nice, but limited. His website is currently down, though it appears that he has obtained a new domain -
www.dvdattache.com - and it is not up yet. Also, ominously, he has not replied to any of my recent emails. I'm an early donater to him and had become friendly with him; he usually responds immediately, so perhaps something is wrong there.
Anyway, this has prompted me to seek out another DVD database program. Looking like Movie Collector right now.
