Here is a link to the RTÉ Documentary on Ballyseedy from 1997.

It's split into ten parts. One of the most interesting historical documentaries RTÉ have done in recent years and ideally RTÉ should repeat it soon. Unfortunately it's not available on the RTÉ Iplayer so fair play to the person who uploaded it.
