How long of a run can you do from the 811 to your TV before you get a signal problem . I need to do a 20' run. Don't want to waste the money if it wont work.
Sounds like a ground problem. This has happened to me before. is the 508 and the 811 using the same outlet? (electrical) . Try using an adapter on the 508 (one without a ground lug on it) and see if the 508 still does it on S-video.
