I know this has been a problem debated in previous threads, but I'm posting afresh as it's happening to me now and I can't see that anyone discovered a solution (other than to do it in DvdStudio instead!).
The issue is that button highlights won't display on set top players. I'm using a mixture of menus that I've pulled through from an Encore 2 project built on a PC (that worked fine), as well as new menus created in Photoshop.
As I test, I tried adding a menu from Encore's own library - and even that doesn't work!
Any thoughts would be great. I'm on a new iMac 2.8
