I recently switched from DirecTv to Dish. Got fed up with DirecTv picture freeze even after replacing all equipment inside and out. I now have 2 DVR625s. I'm not satisfied with the picture quality of the DVR625. It never seems to be consistant. It goes from bad to good but seldom excellent. Both receivers seem the same. I'm not sure if the installers grounded it properly, I'm wondering if that is the cause. Sometime the picture seems to have sort of a trailer and is grainy on picture transitions. Anyone have the same problem. I'm using the s-video connection on both TVs
