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.

Some brands like Cascade produce solid compressed powder tablets. Same general concept as the pods, just no fluid load or pouch

Pod is with liquid, tab is with compresse powder.
