TheaterTek uses NVidia's PureVideo decoders (by default, anyway). I don't know for sure if they make use of HW acceleration on ATI cards or not but if they do, they do so rather poorly. I found I get much better performance for HD playback using the PowerDVD 7.x decoders with my ATI cards (previously a x1600 and now an x1950).
You _can_ actually configure TheaterTek to use the decoders of your choosing, but not through the UI. You have to create either a graph file or an XML file that specifies the filters that should be used. I've never bothered trying to set this up but if you look in the support forums at the TheaterTek website they have some tips on doing so.
