Loksound Powerpack: booster vs Powercab dilemma

[BigDaddy]

After 2 days off, we need a good mystery.

I saw a youtube review (by DG Modelworks) of a Scaletrains Dash 9-44CW with a loksound 5 decoder.  He initially found that the powerpack did not work.  There were some other minor issues and a missing part or two. 

Scaletrains responded immediately to his email and sent him the parts and he did a second review.  He got the Powerpack to work with his Powercab but not with a booster. 

He has done a review of the SB5 booster, so I assume that is what he has.  What could the Powerpak possibly seeing or not seeing in booster use vs Power cab use.

2nd review:

Disclaimer: This is not my system nor loco. There is no further test info I can supply other than what you see on the video.

 Some of the things related to sound are because Scale Trains has a custom file, but their file is a v4.0 file, so it can't take advantage of the v5.0 features, which is how he got all those funtioons independent, and better sounds.

 I have noo idea what NCE might be sending or not sending when you use the SB5 that would make the Powerpack not operate. I wonder if this same problem happens with a PowerPro system.  That seriously impacts some of my planning, as I use nothing but ESU decoders for sound and if I need to, they will get the proper 3 wire Powerpack, not a simple 2 wire stay alive capacitor, mainly because of that time limit feature (I still say 6 seconds is too much - but the one loco I have that has any sort of stay alive circuit runs for more like 30 seconds - at the show I was at, I ran it off the end of a piece of flex track right on to my display table, it went the remaining 4 feet on the table where I grabbed it and put it back down at the end of the flex track, and it would have run off the end of the table a second time if I hadn't picked it up and returned it - where it would have run off a THIRD time. That's ridiculous and completely unecessary, not to mention just asking for a loco to motor across the scenery and right off the edge of the layout)
