TMPEG has good downscaling. Input HD Qucktime reference, convert color space, set scaling options, crop etc. A small amount of noise reduction might help too.
In any case, downscaling from HD often time results in fine texture detail that can overpower the compression engine. It usually helps to remove unnecessary fine texture with selective blurring. Sapphire noise reduction for example.
Could it be that the software scaling produces too much detail and the hardware scaling is softer and better for MPEG?
