Not familiar with that service but assuming it's the same signal being broadcast to each TV somewhere along the line after it's split it's being delayed by one of your setups, either different length cables (that's minor) or something is processing the video signal (such as large screen upscaling the video) which might slow it down a little.

I'd first get two identical TV's if possible or two older TV's and make the most direct connection to them as possible to see if the problem still exists.

They will have to decode the digital signal, and each device uses a different time "buffer" before it shows the decoded signal on the screen. Unless they are the same devices, there is likely to be a difference (cable length may also make a difference even if same device).

One of my kids pointed out that the remotes are different. Are they the devices that you are talking about?

This is the best answer. Digital signals have to be assembled by the receiver before they are shown on the screen. Different receivers take different amounts of time to show a picture.

I've found that my HD channels are a sec or two ahead of the standard def. Same TV, same set top box, same cable company. I take it to be the analog conversion delay.
