hello world, videoplayer sample, what next?

I've read most of the BrightScript Language Reference (and absorbed about 10%, ha), got the hello world app going, and adapted the videoplayer sample to make a simple channel, but I'd like to start over and try building a channel from scratch.

How did everyone else learn brightscript? Can anyone recommend any more 3rd party resources? I'd love to find some more tutorials so I can just keep practicing until things start clicking.
