In the Xampling Hardware section ~17:00, I would say "multiply" instead of "mixing", and "heterodyning" or "frequency-shifting" instead of "aliasing".  Aliasing only occurs on the downsampling n Tp itself.  Mixing more commonly means scaling and summing.

I recall looking at the proof for the Xampling “Union of Sub-Spaces” argument (mentioned at 16:30) and thought it to be deficient insofar as it seems to assume what it is trying to prove.

Very cool, thanks for sharing.
