All it means is that you can't use the "Send to Encore" (dynamic link) for a bluray. Just open Encore and import an exported file. Many users prefer this to dynamic link for Bluray.
As to whether it is true (PC here), no idea.
You could also try opening Encore and use File -> Adobe Dynamic Link -> PR sequence to see if by some very odd circumstance you can dynamic link from that end. But I suspect not.
Edit: I did not find such a limitation in Encore help. The "windows only" appears only once in the pdf - unrelated to this topic.
AFAIK, Steve hated BD so much that he did not include that option in any MAC. The same applies to eSATA. Just some advantages of PC over MAC, or the other way around.
Thanks Stan. I tried File > Adobe Dynamic Link and I was able to send to Encore as a Blu-ray. Obviously an error in the PDF to say that it can't be done on a Mac.
I've created lots of Blu-rays on a Mac with no issues. You just need an external burner, that's all.
Tip: if you need AC3 audio encode it in Compressor then bring it into Encore.
