For DV it's understandable. IMO Dolby and DTS are kinda of a scam (e.g. their lossless codecs). They are welcome to make authoring tools, but the standards should always be open and not subject to unaccountable entities that operate in a unreliable jurisdiction.
The reason I am asking about Netflix is because we got a relatively powerful Chinese Android set-top box (that is supported by a local distributor) and it couldn't play videos in the Netflix Android app or even when logging in via web browser. The distributor said that Netflix support requires a license. After doing some research, this seems to be true for many non-American brands.
We cancelled Netflix and we are not buying any new subscriptions from American firms. I am just curious about the whole license issue.
