Who keeps two or more lists of their movie collection and what do you use for it?

I was reading the past news about the site database data loss a few weeks back and that got me thinking, who has redundant collection lists? I run two lists myself, one being the one here on the site, and another one through an iPhone app called "my movies for iPhone Pro" made by a company called Binnerup Consult. Whenever I get new Blus I scan barcodes into both programs. Interestingly enough though my Blu-Ray.com collection is actually showing a count of two more movies than what I actually have. I may need to delete them all and readd them to find the inconsistency. Back to the subject though, do you run two lists and if so, what do you use?
