I realize I’m coming late to this discussion, but I thought I would put in my two cents worth. I’ve been using Encore for Blu-ray authoring since March, on both Mac and Windows.
Are you creating multiple menu projects?
Yes, although so far I’ve stuck to using the menu templates that came with Encore with only small modifications.
If so, how many menus and how many buttons per menu?
Typically, I use about three menus with an average of six buttons each.
Are they routing correctly when you burn to disc?
No. The routing is usable, but not what I had designed.
Are you able to burn directly to BluRay disc successfully directly from Encore consistently?
Yes. 100% success rate using Sony BWU-200S in an external enclosure with USB connection to Mac Pro. I always test first with BD-RE disc.
Are you able to successfully create BluRay ISO files?
I haven’t tried this as I’ve always burned directly to disc.
Are they actually burning to disc correctly and playing back in the BluRay player correctly?
I’ve completed four blu-ray projects. All of the discs have played successfully in a PS3, but have had menu issues, particularly on the Mac side. In some of the menus, the button highlights are invisible, even when using unaltered Encore templates. The strange thing is, the exact same template works perfectly when authored in Windows. I haven’t been able to find the common denominator in the Mac, as sometimes certain highlights will work fine while others in the same menu (albeit with a different color) are invisible. Also, as others have noted, the incorrect menu default button is sometimes selected and pressing the menu button when playing usually takes you to the wrong menu.
If so, are you running Windows or Mac?
I use both Windows and Mac versions on a Mac Pro (Windows XP via boot camp). Encore’s Blu-ray authoring works better on the Windows side, with menus generally behaving as they are supposed to.
