Have you got all the connections "drawn" as you have them in the diagrammatic representation of your system in the Mconfig programme? If so, type to Type 4 and then download your config to the system. The video input to the G98 from the G68 should be set to bypass as you cannot scale/deinterlace to the G98 component out if you have dissimilar input types. Basically, the scaler is no use to you in this configuration.
