Well, I don't know how a satellite works or how you're going to get the programming, but channel 29 samlip tiansitai (三立電視台) has good programming and I watch the shows occasionally. This is the channel that showed the popular Taiwan A-Cheng last year. They also do some culture shows with countryside visits and narration in Taiwanese. Some of the other channels have popular talk shows and much of those are in Taiwanese as well mixed with some Mandarin. There are several news channels that do a lot of Taiwanese broadcasting.
I know that 中天 news channel (used to have Power News but... what happened with them is a different story) it broadcasts all over the world, but it's in Mandarin.
I'll check later what other channels are in Minnan. My favorite programming is the samlip, they're programming is not humorous, er more serious acting.
