It is a new PVR TV Box with WiFi
Based on the system statistics it is a dual-tuner decoder.
However when a show is recording most of the other channels will not able to watch.

Is it because I am staying in high rise apartment with only centralized satellite dish?

Adult channel? Even kiss scene on fox and hbo also got people complain on Astro FB saying not appropriate. I replied to the person: you should watch Alhijrah, Oasis and Naura HD instead

The thing is, how Astro treat customers is like:
We pay money for your service, yet we get to see advertisements that is slotted in by Astro themselves (not from the original channel provider).
Pay TV service, but we get your service as if we pay very very dirt cheap subscription fees to you, and you use advertisements to increase revenue.

Example 1: You see the Ajax Fabuloso household cleaner advertisement on AXN channel on Astro.
Actually, AXN channel themselves don't air that ad. It is Astro slots in that ad during commercial breaks.

Example 2: Astro Best movies ad being aired on channels that are not owned by Astro, such as AXN, DIVA, National Geographic, etc. Actually, those channels mentioned, they themselves don't air those Astro Best ads. It is Astro slots in that ad during commercial breaks.

To make their TV advertisement team easier to do work, they purposely delay the original feed by 3, 5 or 10 minutes. That is why you see the programme start time, like this: 8.03pm, 10.35pm (supposed to start at 10.30pm, 8.40pm (supposed to start at 8.30pm).
Some programme starts at 7.55pm originally, so once adds on 5 minute delay from Astro, it becomes 8.00pm.
Meanwhile for international news channel, it is delayed by 2 minutes, like the news supposed to go Live on 6.00pm sharp, but on Astro, you see it's 6.02pm.

How to identify if the ad are slotted in by Astro, or not? Quite easy, but not necessarily apply to all channels.
Like for AXN, if you see that ad shows AXN logo, that mean it is originally broadcasts from AXN. The best example is usually Colgate ads.
If you don't see AXN logo on that particular ad, then it is very very likely that the ad is slotted in by Astro. It is commonly those Malaysian brands stuff.
Especially if that ad is in Malay language, in an English channel, then confirm is Astro slot in one lor...

Hmm... There's no delay for HBO (SD & HD) due to the agreement between Astro and HBO. The same practice has been applied by Dreamworks HD on Unifi TV. I think that HBO wants to maintain their channel's standard across multiple regions around the world by proving that they can premiere Game of Thrones SAME TIME AS THE US (aka WORLD PREMIERE). 

No. Only Astro customers can watch it. Njoi customer can't watch it at all.
So it is a loss for Njoi users that they've lost 1 Mandarin channel from Njoi channel lineup.

Maybe they'll add it as part of Njoi prepaid channels offering near future.

I do notice that iQiYi channel on Astro does show some end-2018 programmes, and some is just few months old programmes.
All content from the iQiYi channel are all iQiYi Originals content, no outsource from other China TV networks like Hunan TV, Zhejiang TV all those.
