Having used every beta build so far, with moderate success, today I purchased and installed the production release of EyeTV 4.
It's not good.
There is a significant delay in completing any action, sometimes with a spinning wheel, sometimes just no response
To the right of the menu bar is what looks like a debug facility which wasn't shown on any of the public betas. I suspect this is causing the problem but I can;'t see any way to get rid of it. It've tried deleting the EyeTV app, rebooting and reinstalling, to no effect. I've raised a support ticket, but if anyone has any suggestions I'd love to see them.
