How to use hardware decoder with KMPlayer?

[iieeann]

Hi, I am new on multimedia world and would like to ask pros here about some basic questions:-

1) Is KMPlayer default to use own software decoder for video and audio, and user must configure the "External Video/Audio Decoders" option to enable hardware decoding?

2) What is the difference between "Add System Codec" and "Add External Codec"?

3) There are a lot of filters listed down at "Add System Codec", how to know which one is software or hardware filter?

4) ATi display card says it has hardware mpeg2 decoding capability, do i need to configure anything for it to 'work'?

5) The Creative X-Fi has hardware DDigital and DTS decoding capability, what do i need to do at "Internal Audio Decoders", "Output Mode" or "External Audio Decoders" to enable it?

Sorry if any of the questions do not make sense, I don't even know what to ask T_T...

Thank you

1 Yes
2 "Add System Codec" will search the registry for codecs, while "Add External Codec" allows you add filters which are not registered. I always use "Add External Codec" if possible
3 Check the codec's setting, some filters have a "Enable DxVA" option. As far as I know, Cyberlink decoders support MPEG2 and H264 hardware acceleration, Nvidia PureVideo Decoder supports MPEG2.
4 You should install the proper decoder that supports DxVA, disable KMP's internal decoder and configure KMP to use the external decoder. And do not forget to disable KMP internal video post-processing filter.
5 I dont know...

6) What is the difference between "filter" and "splitter" ?

7) What will be displayed during 'tab' key when hardware decoding is in place? for video and audio.
