I only noticed this bug by chance. After I installed the incremental update for 5.3.4 I imported some movies with HD Lookup. I had a lot of hanging and crashing (in XMM, not w2k)but I kept going, two files at a time. At some point I saw that the first record of my db was deleted - there was no No.1. I thought I might have deleted it, and didn't really keep an eye on it. But now I notice that there are 3 more records missing from the begining - my db starts at No 4.
PS I've mentioned before that Movie ID renumbering doesn't work on my system. I've deleted some records (63, 512 etc)and Movie ID renumbering just keeps these "holes". So now I have 1463 records but the message on the status bar shows "Total Movies in Grid: 1420"
Can you please ZIP your database and send it to me? I want make some tests, because the MovieID Renumbering functions works correctly with my DB of 1490 entries.
