I've seen the video and tried switching from pods (which I assume is the same thing as a tab, just never heard that name before) to powder with some power in the prewash compartment without prerinsing the dishes.

Other's results may vary, but I found my dishwasher would eventually get clogged with the TC approach, even though I clean the filter regularly and wasn't putting in dishes with absurd amounts of food still on them. Since I switched back to pods and prerinsing, the clogging went away. Maybe my dishwasher or the install has something goofy about it, but it was definitely a failed experiment for me. Although I still think the TC argument is a solid one in theory.
