the main problem is that adobe software needs to retain info about a clips enclosing camera root folder which it currently does not. final cut has done this for years and I've never had a problem with numerical MTS files as long as final cut knew the reel (card).
I totally agree, Dan. One thing I really liked about FCP was that it **told** you where it thought the off-line media was supposed to be. This was an enormous help not only with things like MTS files that are all named 00000.MTS 
but also in **teaching** new editors about organization.
Me: "See, little Johnny? FCP can't find your music file because you put it on your desktop and we're on a different machine now. How many times have I told you not to put files on your desktop?" Little Johnny: "I'm sorry. It won't happen again" And of course it did!
