Poor HD playback performance

[Ansy_74]

Hi

If I playback MKV 1080p files in SageTV i get low frame rate and the processor works at allmost 100%.
But if I playbak the same MKV file with Windows Media Player it play just fine at a processor load of about 20%.

I use the CoreAVC .264 codec. And it's specified in the Sage properties file to use it.
I have tried both VRM9 and overlay palyback. And I have 3d and Full screen exclusive mode enabled.

I have a AMD x2 4600+, 2Gb 400MHz RAM, ATI HD2600XT PCI-E.

Any ideas?

Is Sage using CoreAvc or is it transcoding the film? I had a similar problem and when I checked system processes within windows task manager I could see a transcoding process in action.

How do I know if it's using the codec?
If it's transcoding, how do I fix that?

bump for the same question....
also, "I use the CoreAVC .264 codec. And it's specified in the Sage properties file to use it." - how was this done?
