Unfortunately it's not entirely clear what your problem is ("on full screen there are pixels that weren't there before"). Perhaps you could try to explain in other words?
I think it is most probably (also) related to a codec you installed.
E.g. if you're using DivX 5.1.1 check its quality settings: [Start] > Programms > DivX > DivX codec > Decoder Configuration Utility. (If you select "Support Generic Mpeg-4", DivX also plays XviD-encoded movies; "Yuv Extended Mode" should be
deselected if you wish to have access to "Picture properties"
(i.e. Brightness, Contrast and Saturation)).
In this connection I noticed you installed K-Lite
codec pack, which - I've seen - nowadays comes in three versions: Basic, Standard and Full (and there is even an extended version Mega Codec Pack which i.a. includes BSPlayer's
previous build 807). So its unclear what you did and/or didn't install.
General advice and warning re the use of codec packs:
In most situations, you do not need to install codec/filter packs and certainly not every codec/filter that comes with these packs. In fact,
you may run into problems if you install too many codec/filters on your computer. It is
highly recommended that you only install the codec/filters that you absolutely need.
