I'm kinda lost in the codec jungle. Do you apply postprocessing to all SD sources? LiveTV, SD-movies, DVD etc....?
Can you set up all SD-sources to be upscaled with one setting, or do you have to do it over again for each format, such as DivX, Xvid etc....? If so, which formats should be upscaled/postprocessed?
I've also heard that the benefits of upscaling LiveTV is minimal, is that correct? Is it possible to use a splitscreen to see the differences?
You still miss the point - FFDshow (and its postprocessing) is done only for non DXVA material, so not for MPEG2/h.264 TV/Local and not for DVD.
