On the Dynamic Preset extender you have to choose your region for it to generate the graphics. Did you try scolling down? Sometimes there just isn't any on the first page.

Even when I have cable I tell the system I have directv because it provide far more graphics. Each channel has to be edited, but better then edited the channel and name and not having a graphic.

I use SB on every project, I burn through composer quickly to get the blunt work done.

What was the issue with your power on/off? The system does use flags basically to track, so if something got out of sync, it wouldn't be put back.
