Even regular old USB can handle some OTA... The most bandwidth possible IF the entire OTA channel is devoted to a single channel is a little over 19 Mbps
USB is capable of 12Mbps, so couldn't handle that... but if you have an OTA that is doing 720p and multicasting 3 channels, one of them might be under 12 Mbps as a result.
USB 2.0 has WAY more capacity than required to deliver an HD signal from OTA.
They should be able to cleanly have a dual-tuner USB 2.0 stick, but I don't know if one exists OR if Dish would support it if it does.
Yea and if DISH does come out with a single OTA USB tuner module for me that would be disappointing,but why not ,I know when DISH first brought out the Hopper I thought it was at least one satellite tuner short.
