There is a reason why TV stations don't switch off the SD version of their primary channel. There's a renter of set top boxes that has rented out a lot of set top boxes that either cannot receive the FTA HD channels, or require an extra monthly payment to do so. If the SD versions of the primary channels were to disappear, those viewers would no longer be able to view or record those channels, and would have to use another STB or a digital TV.
That company is Foxtel.
If pictures are worth a 1000 words, what is a video worth?
So this is a quick AB between using the auto calibration mic and using REW with the mini DSP mic.
