...asked this before, never got an answer - how can I strip off all collection numbers - I can renumber, but not set globally to "none", so that I have a blank column on my online DB.

search found nada.

...yeah, they are kinda annoying and arbitrary, and there's no way of removing them from online (as far as I can see)

The problem was that I "accidentally" numbered a few of them, then tried to renumber to none, and of course simply gave numbers to all of them.

I may be alone, but I've never needed a specific number for my discs, and with the collection particularly in flux as some are sold/upgraded to HD-DVD/BD, the numbers are even less important to me.  It seems like a less than trivial thing to add to the renumbering scheme a "remove personalization" or some such, but I guess that's for a feature req., not a tech support question.  Like many things with the new software, it takes some getting used to, and quite a few features are a bit more hidden than others.

If there is a way, or if Ken wants to chime in, that'd be splendid.  Still, thanks V for your thoughts.

I personally also don't understand why you absolutely want the numbers to be all gone. If they're all gone, your online collection will still show the Collection Number column but without any contents. That will look sillier than to have numbers there that don't mean a thing to you.
All I can think of is that you don't want people to see how many DVDs you have without counting them.

I think it makes more sense to have a feature requests for the online list to be able to choose the columns you see, such that in your case you can hide the Collection # column.
