I discovered this video on www.taiwan.us.net about Su Beng. The video also briefly goes into the early struggles of the Taiwanese against a string of colonial rulers. It is narrated in Taiwanese and seems to have quite a bit of archival footage.
Click here to see another video of a report on Su Beng done in January 2010 by a local television station in Taiwan. I've seen it before but haven't posted it here.
Once you get clicking, you'll see that there are other videos out there about Su Beng and Taiwan on YouTube.
