Re: For all HTPC folks.
Well 7.3 is the only version that supports both HD-DVD & Blu-Ray. I tried 9 for just Blu-Ray and its so bloated and sluggish. Then when I loaded Win 7 64bit both 7.3 & 9 gave me Areo warnings and would hard lock the whole system. After may tries it was apparent there were many others with the same problem. It seems that ArcSoft TotalMedia Theatre 3 Platinum had there act together and had Win 7 support right off. Once I loaded it I swapped HD-DVD & Blu-Ray back and forth and it played them great with faster load times.
