Media Manager and error 47

Last week I started a thread to discuss the improvements of the Media Mangager in FCP 5.1.2. Bottom line...it's much better than it was and seems to handle speed changes with no problem now.

Two issues that I have found still remain:

1. Any source without reel #s won't be managed properly
2. Any source that has a frame rate other than your sequence frame rate won't be managed
properly.

Both of these issues can be worked around of course.

Which raises this question...what is error 47 that comes up in the MM when it hits one of these clips that it can't manage? I assume is related to incompatible frame rate but was wondering if there is a list of these errors for FCP listed somewhere?

Thanks.
