On the U9 model and here:
"Rich Cinematic Surround Sound – Dolby Digital Audio
NEO U9-H brings the full-theater sound to your living room. Fully licensed Dolby Audio delivers unsurpassed, vibrant sound quality that brings your entertainment to life."

This raises two questions for me:
1 - When it is said that the U9 has a Dolby Certificate, the question arises as to whether the Dolby in U1 is without a Certificate?
Is the Dolby certificate defective in the U1 model?
2 - If Dolby Audio needs a
full certificate, then why hasn't this certificate been issued for DTS?
Is the DTS Audio certificate incomplete?
