Larry - Great rundown of the setup. I too have the Samsung 46" (Tantus model) and I love that TV. The wife thinks it's great too and that is saying something as she doesn't get into the whole electronics thing.

"I get exasperated sigh code number no64U "
HAH!!! I know that sigh code. If I could only program it into a macro button on the remote and have that sound play over the speakers I could save her the trouble!

Regarding your Comcast cable box, do you have the new one they are test marketing with the DVR capability? If so, curious as to your impressions. I received a call from Comcast about it but decided to hold off after they told me you could not view a different channel while recording.

Enjoy the system. It's the best toy you're gonna get for awhile.
