No. Just a difference in how long it takes each provider to uplink and process the "local into local" signals. Understand that the signal must be received by the local "pop" unlinked, processed, downlinked, and the uplined again to the sat you actually receive.
I find that DirecTV is about 10 seconds behind watching the same station OTA with an antenna. I also find that that my local OTA is about 15 seconds behind the NFL ST of the same game.
Unless you are gambling in real time or something, what does it matter?
