So glad this happened I had my finger on the trigger aimed at a ztrip since it dropped. I am using the 2.1 beta with a Rane 62Z and 2.4. It seems to work fine until i close Scratch Live: it just hangs indefinitely. I have not been able to successfully shut SL down after using the beta with the 62 for more than a few minutes. I noticed that SL has to rebuild overviews for several videos since the upgrade. I'm not sure if these two things are related but my first thought was that I played so many videos that needed rebuilt overviews that on shutdown SL was taking a long time to write the database (?) so I let it sit and do it's business overnight and it continued to hang for several hours. I just wanted to report my experience so far. That 62 is money.
