        No conflict at all.   -E processing is done after the quantization
        tables have been used.

        Makes a lot of sense.   -E goes thru the output of the quantization
        process to make it more efficient to encode.

        Well, yes.   "-K hi-res" is the same as "-H" though so I'm not sure
        why you'd want to use both :)

        You can, if you wish, create your own custom matrices and use them
        with "-K file=path_to_your_file".   Thus you can take the intra (I
        frame) table from the hi-resolution  side and combine that with
        the non-Intra (B/P frame) table of TMPGEnc.  

        I've attached the custom file where I did just that.  The I frames
        end up being bigger (but there are only on average 2 of those per 
        second) but the P/B frames become smaller.   Overall the image looked
        very good (but not having done double blind testing against a default
        encoding that's not saying a lot ;)).

        Cheers,
