mencoder_mt.exe paired with AviSynth not loading CPU 100%

[Seff]

First of all i'd like to say sorry if this topic was already mentioned elsewhare on the board.

I have the following situation. Sometimes I need to use Mencoder/AviSynth combo to encode files on the fly, not just Mencoder alone. And here is what i've noticed:

I've got my hands on a 1080p anime series which I needed to encode with MEncoder/AviSynth because for whatever reason MEncoder alone would not display external subtitles. I loaded MEncoder+AviSynth and found that the subtitles displayed just fine. However the video began to stagger in just a few seconds. I looked at the buffer and found out that it was empty. I switched to Mencoder alone - the buffer was fine (but no subtitles ;p) and CPU was loaded 90-100%. After that I switched to MEncoder+AviSynth again and opened up Windows Explorer to find that mencoder_mt.exe only loads the system up to 65-75% (just like the "standard definition" mencoder.exe should). Is there any possibility to make it to 100% maybe in the next release? Because I think this is the reason why the buffer is always low.

This has nothing to do with pms but with the 3rd party codec you have installed. If it doesnt support mt you wont get 100% load. You can try CoreAVC, to my knowledge the fastest h264 decoder.

Yep, that was just the case. Switched to CoreAVC (the new version has just been released for those intersted BTW) and got what I needed.
Thanks, Pepijn.
