We've just released CatDV 8.0.6, available at http://www.squarebox.co.uk/download1.html. This fixes the crash when using Apple's MPEG2 component to import movies into CatDV under Snow Leopard, as well as one or two other minor changes.
Am I glad to see the Cow add this forum! CatDV has been one of the best kept secrets for years, providing many of us solutions to file transfers, tape captures, and scene cataloging.
Disclaimer... I don't work for Square Box, but I love this software! Rolf is always tweaking it to keep up with the new toys. Glad to see the latest update.
Sorry, we're not always very good at keeping the update check up to date! We plan to automate that but in the meantime, checking the download page http://www.squarebox.co.uk/download1.html is the best way of making sure you have the latest version.
