Just downloaded and installed the db query plugin and like it a lot.  But I have a couple of questions.

1) I have 1458 dvds.  The Personal Information query window says there are 1452 profiles that match.  What is the discrepancy?  Does the table actually show all the dvds?

2) Why would 9 or 10 entries not have a date listed?

3) Sorting.  If i click on the Title column it appears to sort correctly.  If i click on the Production year column it appears to sort correctly.  But if i click on the purchase date it does not sort correctly.  Is there something that i have to set?
