I've simply given up. All things were correct with one minor adjustment. DVD worked well however the satellite signal came in red then green tint and then consistently intermitent. No adjustment was possible so I simply went direct HMDI from satellite to HDTV, optical from satellite to 990. Back to perfect however a lot of money spent not to use 990. If any problem with the DVD I can also go direct from DVD via HMDI/DVI to HDTV as well.
