Back to looking for HD DVD playback software

htI've been playing HD DVD movies with my Toshiba HD DVD player- which does a fantastic job. However, for mixed-media, I really want to get my HTPC going again. It should do everything, right? Playback software for HD DVD is not common- but oddly- there are probably more choices now than when HD DVD was still viable. Below are the software I have heard work:

• Arcsoft Total Media Theater. Though the website doesn't mention it, I have it on good authority that it does work.
• PowerDVD. I have an old version that actually works. The software is pretty clunky, but I have used it. The new version has dropped HD DVD.
  
• Corel WinDVD. Supposedly even the latest version supports HD DVD
• Nero 8 with BD plugin. The latest version of Nero (9) does not support it, but 8 may still be available.

I'm leaning towards Arcsoft's TMT3, as it was recommended by an HTPC person (who also share a fondness for AMD processors).
