OK, I made an error. I have an A4 and an A50 receiver. The 621 code works great with the A4. However, the A50 is a part of the home theater and that is what I want to control with the remote. The A50 receiver has dolby digital and that is why it is a part of the home theater. David, do you know why Sony left out the discrete code for OFF and ON on the A50? I can't believe how they ruined this receiver. They also left off the S-link interface, which it the only reason why I need a universal remote in the first place.

Thanks.
Dan
