Earthed series is good and so is New World Disorder as it has a mixture of the disiplines (mainly the ones youve listed). Illusionary lines is another one, ive just got it. That focuses more on the world cup scene, so footage from most of the world cup stages and a few sections of general riding.
Having spent an entire week at the worlds watching pretty much every dvd we were selling I'd say for DH/4x Between the tapes (I've seen it about 50 times and still like it) or Illusionary lines which is a bit less documentary style.
For freeride CKD is a bit of an underated one or obviously NWD 7 is amazing.
Roam is good for arty farty type stuff but i still think the Collective was better
If you want value for their money there's Earthed box sets available now, all 4 for £25 instead of like 70 if you buy them individually
