Encoding or decoding issue. what sharpens the picture?

[spx]

Hi guys.
I've stumbled upon an issue with encoding (or decoding) the video, which i'm currently trying to 'rip'.

Here is the problem:
Source is ntsc animation dvd. I use d2v->avisynth->megui+x264 combination.
When i'm making a preview screenshot of certain frame via avisynth editor (AvsP program), and then encode video, i get weirdly different results between those two. And these results, apparently, absolutely don't have anything to do with x264 settings, at least it's not quality or deblock issue. x264 profile is high @4.1 with -1:-1 deblocking and 14 reframes, nothing else changed.

I am using MPC-HC player, and i've tried to playback the encoded file using the LAV and FFvideo(libavcodec) decoders. They give the same 'BAD' results. However, VirtualDub and AvsP previews show same 'GOOD' results.

I'm really puzzled about what could possibly chage the picture this way (it looks more sharp, and juicy-colored, however it feels more flat and lost of details)

here is the comparison between avs output and x264 decoded version:

I have changed the MPC-HC output setting from Enhanced Video Renderer to Video Mixing Renderer 9 (renderless), and now it looks exactly like source.
It can be found in "Options->Playback->Output->DirectShow Video".

So.. it's a player problem, i'm feeling sorry for posting in codec section now :|
Thanks for assistance, LoRd_MuldeR.
