Press the "live" button, this may help but it won't sync up to other tv's due to the DVR buffer.
How do you like the Westinghouse 37" LCD. I installed one the other day and I have got to say it was pretty bad. I installed a SD DVR and a H10 HD both by DirecTV. The HD looked ok. I am not sure what the contrast ratio is, but it looks like 500:1!
