My new zgemma works perfect, however my dads and uncles dm800se both break up sly movies SD. Tried a new image in case it was new drivers etc required still the same! Now is there something goinf on in the uddingston server area? As its on the dm800 that's affected! Tried new tuner too, still the same.there's also only bare minimum on the cable feed from the street! Baffled!
