Anyone Using DVDit Pro HD for Authoring?

Is anybody out there using Sonics, DVDit Pro HD for burning HD discs? If so, what are your thoughts? I've been using DVDit Pro (SD) for many years and have been pretty happy. It's only a $200 upgrade for me and seems to be the most cost effective jump into Blu-Ray authoring. Any feedback would be greatly appreciated.

Thanks,
Mark
