You use back your old Astro PVR decoder or new NJOI decoder?

Im using my old Astro PVR decoder and that time it was just free to activate Njoi without any setup whatsoever.

I dont see any difference on the sound or picture quality of SD channels on my Njoi compare to my old astro account.

Video signal passthrough to my AVR for SD channel is 1080i with 2 channels sound.

Similar for HD channels, they are 1080i but surround 5.1 channel sound. 

Please check your settings.

If there is a poor picture quality i should be able to observe since im watching these SD channels on my 50" 4K TV.
Another thing there are more than 2 HD channels, at least 5 are free (Xi Yue, Maya, eGG, GoShop, GoShop2)

Paid HD channels available now are WorldCup 1 and Worldcup2, Tara HD, Raya HD,Vinmeen HD, Bollywood HD, Quan Jia, AOD, Oh!K, tvN, Boo, WarnerHD, Kix HD.
