Directshowsource and directshow filter posprocessing

I was wondering if there is a way how to enable video postprocessing by directshow filters used by directshowsource in avisynth. According to what I have found on the internet it looks like avisynth disables all kind of video postprocessing by directshow filters. I would especially appreciate if deinterlacing was done by built-in filters in Win7. I donīt want to spent time on analyzing different types of video and write appropriate scripts if I can simply use the output from the directshow filter and encode it with respective framerate. The result has an excellent quality and it saves a lot of time before encoding.

Another advantage of using directshow filters is that I donīt have to worry about the video content (sometimes I transcode h264 in ts from DVB-T broadcast, later itīs DVD NTSC interlaced source). All these are supported natively in the latest windows and I donīt see any reason for using different filters as it was the case in previous years. I also feel that the quality of deinterlacing/postprocessing is superior when using WIN7 native directshow filters to methods available for avisynth. Itīs possible of course that I didnīt use the best deinterlacing method available for the given purpose but my goal is to simplify the pre-encoding work as much as possible while still enjoying the excellent video quality that avisynths gives...
