    Does this postprocessing configuration should be repeated in tv section?

    I tried to use ffdshow rar filter for postprocessing but I think it was not enabled for TV?
    Does anyone got it working for LiveTV?
    Thanks! =)

    So does that mean that ffdshow or LAV can and should only have RGB32 ticked for the Output format and the GPU driver can then change it to YCbCr if necessary?

    And can and should the Output Levels setting in ffdshow or LAV just be set to 0-255 and then the GPU driver can convert this to 16-235 if necessary or must this setting be correct for the display being used in both the codec settings and the GPU driver settings?

    No need to only check RGB32 as possible outputs. It is the preferred format you want to send out. If - for whatever reason - this is not possible let ffdshow decide. So no need to do anything here. Keep the defaults. Just select your preferred output and you are done. Same for LAV. We do the postprocessing in ffdshow. No need to customize more than needed in the codecs.

    If for a TV you do YCbCR and/or 16-235 with the GPU just keep the output to 0-255 in ffdshow and for LAV just don't let it do anything with the color range. The ffdshow postprocesing will do everything. Keep the setup simple.

    Holzi: I don't use MP for TV. So I can't help your here. You probably need to add .ts to the extensions or create an own profile for it. Just a guess though. So it's up to someone else to help you out here.

    I don't see any way to set RGB32 (or anything else) as the "preferred" format/output in ffdshow or LAV. Are you suggesting that if everything is ticked, it will "prefer" RGB32 automatically and only use the other formats as fallback in case RGB32 doesn't work?

    Ah OK, thanks. What about if I'm only using LAV though?

    For LAV only you probably only have to check RGB32. Just give it a try...

    Sorry but I don't understand that. If ffdshow should have everything checked so that it can fallback to something else if RGB32 can't be used for whatever reason, surely LAV needs the same? The problem is that LAV doesn't have a "preferred" setting, unless perhaps it has RGB32 hardcoded as preferred.
