I'm looking for any DVD Authoring software that is better than Adobe Encore and that would compete with Apple's DVD Studio Pro.

After having a strop some time ago I moved away from the MAC, Final Cut Pro 3 & 4 and DVD Studio Pro 2 in favour of using a PC, Adobe Premiere Pro and Adobe Encore (cost and speed being two of the main issues) however, after having been used to the flexibility and options available in DVD Studio Pro 2, (which is now onto version 4) I find Adobe Encore extremely basic, and some of the simple things I used to take for granted in DVD-SP2, like multiple angles and variables just don't seem to exist in Encore.

Therefore I was wondering if there were other applications out there for DVD authoring on the PC that are better than Encore, because if I end up going back to the MAC to get back some of the features I'm starting to find I need, I'm going to end up having to spend a minor fortune to upgrade my current MAC system to compete with the workflow speed I have with my two PC's.

Thanks in advance.
