I believe the first episode of Flash was available on the Takaratomy youtube. Forget if it needed a Japan proxy though.

Pretty much all of the older seasons (except for the Katta ones) are hard to find (especially in a decent quality). There was used to be a torrent that was always shared around...but I hate torrents in general, so I never got it.
