Genius of Photoragphy

Dunno if many remember this wonderful six programmes series on the Beeb from a few years ago but whilst doing some disk house keeping, I have discovered I have all six in .avi format.
I was going to ask, how might one store these, online? ;)
From 'download' folder into, say 'documentaries' folder on the hard drive.
I tend to watch most stuff on the laptop, but occasionally run a cable into the back of the TV for movies etc.

Feng Shui'ed recently, and loaded a lot of dvds onto the external hard drive, and flogged the dvds.
Most downloads from skull and crossbones places get watched and binned, but often there's one worth keeping for posterity.
