Is this poossible to use P4?

[AlexeyS]

Is this possible to use P4 2.4 GHz to decode 1280x720 video ecnoded with Nero Recode (AVC)?

What decoders/splitters I should use?

Haali Media Splitter.
ffdshow or Nero Video Decoder (if you have NVE installed, you have the Nero decoder. It borks on VFW x264 encoded files, however).

P4B (I assume it's B, don't know if there was a A 2.4GHz) @ 2.4GHz should be able to handle that res fine, but a high number of b-frames or intense softsubbed effects could lag it.

I usually encode with Standard options (2-pass) with Nero (HDTV AVC Profile). How to set up FFDSHOW to play HDTV AVC video without lags?

There is no setting up to do...just set the H.264 decoder to "libavcodec", and turn off post processing, and you're good to go.

How to turn off postprocessing? Just have to remove check "Postprocessing"?

Tried to do this - still have lags.

Set player priority to AboveNormal, kill unnecessary tasks. Yes, unchecking PostProcessing will kill it, though I still find it odd you have laggy HD AVC on a 2.4Ghz P4. You could try one of celtic_druid's performance orientated builds of ffdshow perhaps.

AFAIK the p4 optimized dll is b0rked, I've never been able to extract it before
the AMD one extracts perfectly though

Wouldn't the bitrate (not disclosed in your post) being too high cause this? What is the bitrate you are using? Try a short clip at different bitrates and see if lowering it helps.
