One offfdshow's unique features is the ability to enhance the quality of video. Most of the videos we watch are heavily compressed, and some of them have pixelation, which is especially noticeable on large LCD screens. You can reduce this by enabling deblocking. Right-elick on the playing video and select Fil ters > ffdshow Video Decoder. Check the box that says Postprocessing.

To get an idea of how much the quality enhancements are affecting the video, check the Only right half box. Check one of the processing modes available and set a processing strength using the slider. When you're pleased with the quality, uncheck the Only right half checkbox and click the Process whole image checkbox. Click OK to finish.

Some of these processing methods can be highly CPU-intensive, so you might want to select a different processing method such as fast SPP deb locking. Lowering the processing strength (by moving the Processing Strength slider) can also help.
