We have a S2ST (LT) and S2DT and are thinking about switching out the S2DT for a TivoHD. There's number posts that says the HD unit doesn't support satelite, but isn't really clear as to what isn't supported. We use Dish for some Chinese channels and it's been working well with the S2DT and the IR blaster setup. If you go TivoHD, will we still be able to do this? Does the THD still have the capabilities of recording SD via the S-Video/IR Blaster method?
