Windows 7: WMP not displaying entire video library

I am running Windows 7 Professional 64bit & WMP12 64bit.



When I build/rebuild my CurrentDatabase_372.wmdb it grows to exactly 2GB (2,101,140kb) and stops growing and no new files (in this case video files) are added to WMP after this limit is reached although the "Updating media library..." message in WMP continues to display. (Note: all video files are in same folder tree; top-level folder is specified as library; missing media folders are alphabetically the last of the sub-folders; music & pictures (much smaller libraries) seem to have completely populated successfully).

I've deleted the database and recreated it several times with the same results.
I've checked for file size limitations (both OS and WMP)...there does not appear to be any.

Question: Does MCE use CurrentDatabase_372.wmdb for videos?

I ask the above question because ALL of my video files (beyond those that appeared in WMP) are still in MCE after deleting the CurrentDatabase_372.wmdb. Deleting CurrentDatabase_372.wmdb removes all videos from WMP but not from MCE, so MCE doesn't appear to be using CurrentDatabase_372.wmdb for videos. If this is the case it's a positive.

Question: Any ideas as to why my CurrentDatabase_372.wmdb stops growing at 2GB and all specified files are not loaded into WMP? What corrective actions can I take?
