My copy of The Winning Streak was taken from Michael Bird's own video recording made when the series was broadcast back in 1985. The tapes have been transferred to DVD - two episodes each on three disks - and they reproduce remarkably well (thankfully - since it is probably the only way anyone will get to see the series again.)

The DVD is 'region free' so it will play anywhere in the world.

As for any prospect of YTV releasing the series commercially ...
