Well we thought we had things starting to go well with Encore after we figured out that the buttons would turn into blobs and figured out a workaround, but alas, more things just don't work.
One of the supposed really cool things about Encore is the ability to build your entire DVD in Flash. This allows you to upload a working version of the DVD in a flash based format for a client review. Well, we've tried this multiple times on both our Mac Pro Quad 3.0 and our new Octo Core 3.2 and all Encore does is build maybe 10% of the project and then it simply hangs. Really disappointing.
Supposedly this issue has to do with Leopard and the latest Quicktime, but the Mac Pro Quad 3.0 is currently running Tiger and it doesn't work there either.
Also, we've discovered that Encore CS3 is incredibly unstable on the new Octo Core 3.2 as well. Crashing at least every 10 minutes if not more.
