Why is Sea Mead M3 better than HD600A and H7 II? Hass quad-core processor

Hass Quad core, why M3 is better than HD600A, H7 second generation?
Of course, good or bad, your views are not necessarily the same, but people M3, support DTS, AC3 hardware decoding, HD600A, H7 second generation, are Hass quad-core, but can not decode, made everyone see the local blockbuster, there is no Voice, then, various gods in the altar, various settings, various APK software installations for software decoding,
I will ask, why is this?
DTS and AC3 technology have come out into the ordinary people's home. At least 10 years have passed. Can't we solve it?
Then I will ask, which is better decoding technology? Haimei Di M3, H7ii, HD600A, is not a nanny?

H7II, HD600A quad-core, all 3798M chips, GMALI450 GPU ah, no heavenly ah?

After thinking about it, it is still an issue of authorization.
However, for Ac3, all previous DVD players support it. Although Medic did not write support for Ac3/dts, it should not limit the root and allow private experts or users to crack it. The official concerns about the issue of copyright are to let go of the people. Originally wanted to buy two in other rooms, this product is no longer considered.

Just bought in the JD H7II, I also returned, and can not accept all Quad core Hass, but also than my H7 single-core, or even 107% I bought more than 10 years ago is bad?
