I'm glad that I am easy to please. I'll stick with my DC, put the locomotive on the track and watch it go. I have operated on layouts that had DCC with sound, it's nice, but I have seen so many posts with problems with DCC, I'm glad that I am not interested in changing. I am a lone operator, and for my type of layout, DC works fine.
... This is why I don't own any MTH locomotives. They force their proprietary system on you. You can do some basic programming of their stuff on DCC but last I heard to get full command of all functions you need to use their DCS system....
FWIW, I think it could only benefit MTH is they offered their decoders separately. People would be more inclined to purchase his DCS system if they were able to retrofit their existing fleets. That would also mean he would sell more DCS equipped engines. Some features would be mnice to be able to access, but not nice enough I would want to sell my entire fleet of engines, plus my DCC system, just to have them. That, added to the QC issues of MTH, and their limited support, means I will never have his system, unless somebody gives it to me. And I don't think that is going to happen...
Anyway, I've been watching the "Woes of the Big Boy" saga for some time, and I know I would have dumped that engine long ago, and got something that caused me less trouble. If nothing else, I think the OP shows a lot of determination to make his engine work like it should (or even work at all).

But, hypothetically, could you put some other brand of decoder (not necessarily a sound one, either -- just to control the engine) into an MTH loco? (Although hypothetical, this is a relevant question for me, assuming that on some occasion I might acquire a used MTH loco...)
DCS is not DCC. Simple as that. MTH doesn't force anything on anyone. They are very up front that DCS is not DCC. To purchase a $600+ MTH loco is a choice and there is plenty of information available both from MTH and the modeling community to help one make the choice. MTH entered the HO market using their proprietary DCS command control system which was already well-known and proven in the O-gauge market. The fact that HO modelers can run MTH's HO locos at all using DCC command control is a fairly generous concession IMO. For my own purposes and personal tastes, I am satisfied with the performance of my MTH HO locos using NCE PowerCab. The man in the video is clearly frustrated and feels cheated, but it is well-known that "tweaking" and "programming" MTH locos as if they were fully DCC-enabled does nothing more than screw them up.
