Framestep and screenshot problems

[Gadjan]

I need precise frame capturing for mkv/x264 files but I can't use BS player at all... Frame by frame does't work for me when I use any renderer (overlay mixer, vmr7/9, renderless, evr). It only works when I use internal renderers but even then there are number of problems:
- Screenshots are not usable with any internal renderer, colors are wrong, somehow yellowish. I tried checking different combinations (YV12, YUY2) without luck.
- If internal directdraw or overlay are used, captured frames are not what is shown (what I see at that moment).
- Framestep and precise capturing works well only with internal rgb overlay renderer, but then again picture is yellow, and also player crashes more frequently than with other renderers.

When I use vmr7/9, renderless or evr, colors of captured frames are right but it's worthless because then frame by frame doesn't work...

Is this normal behavior or some problem with my installation? I tried unchecking "seek by keyframes", of course.
I use version 2.57 and windows XP SP3.
