Can't answer the last two for you, but for the first question you will want a plugin called Database Query that was created by Mark Harrison.  It's a fabulous plugin that will let you query for all sorts of missing data.  And that's only scratching the surface of what it can do.

I love it and use it regularly.

You can get it here: http://mysite.verizon.net/MEJHarrison/Plugins/Plugins.htm

Thanks! I'll try that. Mine seem to be getting "squished" on the "main" section of the DVDProfiler app, but look fine in the side listing.

I tried the Database Query but I can't find a way to search for titles missing cast - can you help me with setting that up? The coverart scan worked great though!

Quoting SPIDERone:

Quote:
* Can I filter out only titles with missing cast (no cast at all), coverart (either front, rear, or both), or other missing details? So I can go back and add it now.

There is a possibility with XML/XSLT if you are up to it:

Make a XML-Export of your collection (File -> Export Profile Database -> Accept -> Single File) and put it e.g. to \Users\$Username\Documents\DVD Profiler\
copy the filter.xslt at the bottom of this post and save it to the same directory.
Now get DJ Doena's excellent XsltTransform and put the two small files in the same directory as the XML and the XSLT. Run the EXE and a window pops up with three queries: XML and XSLT should be obvious, as Output-file I suggest you navigate to DVD Profiler\Flags and name it e.g. no-actors.lst
Press "Process" and wait a few seconds depending on the size of your collection.

Now go back the Profiler and go to Collection -> Flags -> Load Set and choose the saved no-actors.lst and et voila, all titles with less than one Actor-Entry get flagged.
You can of course set the number higher for entries with suspicious few Actors or look for Credits/Credit to find profiles with no crew etc.

Only "no coverart" can't be done with this, just open the "\Users\$Username\Documents\DVD Profiler\Databases\$Databasename\Images\"-folder and look for the generic placeholder picture.

I set up tags for missing data, then went through my collection once to set them for each profile as appropriate.  Now, when I am in the mood to work on scans or credits, I filter on the tag and pick a profile to work on.
