When using TheaterTek to play 1080i .ts files, I get a little stuttering. When using PowerDVD with hardware acceleration enabled (ATI x1600 card), it is fluid...no stuttering.


So, am I right in that TheaterTek does not take advantage of hardware acceleration for the ATI cards?

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.

Yes, and what a shame that is. I was ready to fork over the $70 for TheaterTek, and still would, if there playback was better with my ATI X1600. The controls in TheaterTek are way superior to PowerDVD, but they can't match the playback (yet). I am going to email them to see what they say.

Am I correct in that using DXVA utilizes some the ATI GPU features, but not all? In other words, without a checkbox to enable hardware acceleration, I will not have full hardware acceleration.
