Hmmm... Not sure if this would help, but no harm trying...
For those who is confident that they are using DCSS LNB instead of Universal LNB, try this Update satellite frequency by pressing home>Settings>Manage Satellite Frequency.
   
*This option is only available and only will work for DCSS LNB users only. It won't work if you are using Universal LNB and SatCR LNB on the satellite dish.

If still cannot, then I dunno how already....  It's time to contact customer service then.
Let me break it down to you:
Before this my PVR using 2 cable to connect from dish to PVR...
This suggests that you were using Universal Dual LNB. It is the same thing as the usual Universal LNB, it's just that it has two dedicated, standalone satellite outputs from the LNB.

when I change my PVR because of faulty, the installer only using one cable from dish to the splitter then the splitter have 2 cable to connect to the PVR. The installer also has changed something in the antenna.
Seems like the installer have changed your LNB to the new DCSS LNB, yet you still experience 11.7-12.75GHz signal conflict?  :confused:

Erm, I suggest to get a technician to come over your place and check what's going on.

What did you do, until you're able to watch those channels?

Assthrow just have latest software update for PVR.  Beta version?

Quick silly question..if I decided to change to Ultrabox, I will tied 24-months contract with Astro right? Am I still able to change packages after that? (While keeping the bill RM100+ still)

Regret already? Too late, bro 
Here goes the saying "Since the new Ultra Plug & Play does not need satellite dish, so it must be a good product."

Another new, new Astro remote control model? Lol, how many remote control models they want to have? 🤣🤣

No. It seems that the one with dedicated Netflix button is going to be the next Ultra Box's new remote control model.

Aduh, i wonder later on, would many existing Ultra Box users suddenly asks Astro for getting the new remote control, just because it has dedicated Netflix button, and also rewind/forward/play/pause buttons too... 😅😅😅

Curious to know ART channel rating as this channel has been in Astro for so many years.

Updated to 21.2.5.29 with force update....

Any special on Maharaja @ Chakravarthy channels? Are they showing specials similar to those special Deepavali programs in India?

Vijay TV is missing....? Or am I not getting the answer ... Konfius

I assume what you meant by GEC means General Entertainment Channel and APAC means Asia-Pacific?
Oooh... I have some questions...
If that channels is India feed (not APAC feed), does it means the viewers will need to add 2 hours 30 minutes on their own?
For example: The ad says programme will air at 9:00PM. But due to time difference between India (UTC+5:30) and Malaysia (UTC+8), the programme will start at 11:30PM here instead.
Or, Astro will delay the entire feed by 2 hours 30 minutes like what Astro did to Makkal TV not long before it ceases Please don't     

Also, can help to verify the table below...? Correct me if I'm wrong. 

Channel name	Ch. no	Source/Feed
Colors Hindi	116	Malaysia
Sun TV	211	APAC
Sun Music	212	India
Chutti TV	213	India
Star Vijay	221	Malaysia
Colors Tamil	222	Singapore & Malaysia
Zee Tamil	223	APAC

Getting Malaysia feed actually costlier for astro
Then why Astro bother having Malaysia feed if it is costlier? Why not just take APAC feed or India feed?
My guess would be before or on Deepavali day itself 
5-10 mins delay..., that one haihh, Astro where got so kind-hearted gives you no delay feed one. Confirm they will delay the feed by few minutes for the sake of advertising complying censorship guidelines
