I follow Newcastle as well as Boston and the Toon have released a couple of DVD's this year, obviously the 5-1 victory over Sunderland is one but the 4-4 draw with Arsenal has also recently been released.
As has been said, DVD's of matches are not always released to commemorate wins, they're put out there for memorable matches as well, and that's not small-time in any way at all. To think that way is small minded in all honesty. It's just good business sense.
And as you can see, there's clearly some demand for this DVD so it looks like the club have made the right decision.
