The videos I have are:
The Collective - The Collective
The Collective - ROAM
The Collective - Seasons
These are probably my favorites. The do amazing camera work and the films are shot from an artful perspective. They also have a lot of commentary from the riders.
New World Disorder 6 - Unchained
New World Disorder 7 - Flying High Again
New World Disorder 8 - Smack Down (this is the one you and Marc were watching)
The Disorder series has been around for a while and they make really good films. Mostly big-mountain freeriding with some urban/dirt jumping mixed in. Lots of cliff drops.
Kranked 5
Kranked 7
Similar to the Disorder series in quality and content.
Earthed 4
Earthed 5
These are mostly coverage of World Cup events like Downhill and 4X with some other clips mixed in. They're actually really interesting to watch and it's amazing to watch pros doing what they do.
North Shore Extreme 9
This series appears to be from a small production company but they have some big-name pros like Richie Schley and Wade Simmons, along with some really good local riders. Obviously, the focus in on North Shore riding.
Chainsmoke 2
Like Disorder/Kranked. This one is a bit dated now.
So that's my collection. I usually grab new videos whenever I can find them.
