This may be different but I've had my 4mp cam not viewing correctly in BI when changing from 2mp to 4mp. I tried deleting and adding again using the export/import feature in BI to get my settings back but it still didn't show the correct live view (recorded looked ok). The only way I got the correct view was to delete and then manually add back all the settings. It was a pain in the butt but it worked. Again, what you are doing is different but you could try adding it back into BI manually and see if it helps.
