Although, looking at that phpDVDProfiler chart makes we wonder if there is a problem somehow, since 2009 is shown with less than half of that (109), which seems a bit low )
I was thinking more like an incomplete update or something like that... I hope it's not actually changed in the profiles. I'll have to check it out again within DVD Profiler itself.
You can also check if you have any conditionals in the localsiteconfig.php. For examply I only count profiles that have a purchase price > 0.00 to filter out all child profiles of TV sets.
