Astro is vulnerable to satellite failure and Netflix etc depend on the international cable actually working.
Both depend on foreign governments to function.
Terrestrial TV is actually a reliable fallback

Yeah, i do kinda miss the music video slots. Nowadays it's only on Al-Hijrah (islamic) and Okey (regular locals)

This one I don't really agree.

Satellite technology is very reliable actually, in fact even more reliable than undersea fibre cable to some extend, especially when it comes to backup solutions...
Service availability are at least 99% up-time, meaning the possibility of it to have failure is very very small till the point that you no need to think about it.

MYTV are primarily relies on C band satellite backhaul via ABS 2 satellite to deliver its channels to the digital TV platform.
So if, ABS 2 satellite occur some failure, then whole Malaysia no more digital TV broadcast, which is so very unlikely to happen.

When you see Measat satellite has major failure?
Even RTM's TV1 and TV2 channels, as well as TV3 also relies on Measat 3 C band as backhaul/to provide channel feed to Sabah and Sarawak.
You don't hear that there's ever any broadcast disruption over at Sabah and Sarawak due to satellite failure, right?

If there is a failure to international undersea fibre cable or satellite, they can route its services to other undersea cable providers or other satellites as a temporary backup, so that service disruption can be minimal r even unnoticeable by users.

Agree with that. Satellite TV (C-Band) is extremely reliable, with 99.995% uptime, after considering sun outages that will happen twice a year. Ku-Band is not reliable whe compared to terrestrial TV/C Band due to weather issues. Sun outages is different in each area so if one area is affected, it will typically not affect other. Only very selective users, like the military, require more than 1 satellite as they require 100% uptime. DTT is very realiable too, but however it is subject to transmitter outages. But since no one want to have 2-3 meter satellite on their house due to legal issues/looks ugly in some situations, DTT remains the best system.

Hi, guys. I just got a new TV with dvb-t2 built in but when I search with the tv, no channel was found. Any particular reason for this?

How to check the coverage? Puchong is it covered?
*
puchong is covered. but make sure u got a proper antenna+cable & pointing to the right direction.
check the signal strength & quality first.

Satellites are potentially vulnerable to an accident or attack in the geosynchronous orbit filling the orbit with shrapnel as in "Gravity"

C band is under threat from the US, who want to use the band for 5G

Any rule of thumb how high it should be. My distance from the transmission tower is 80km. What kind of booster work?

Try readjust the antenna.
Make sure to monitor the signal strength % readings while adjust.
Adjust until you get the highest % readings possible.

Woah 80km?? Show us a pic of your antenna.
How high.... Err, just install it on your rooftop, as high as you can.

This one really effective and powerful? Looks like this booster not so strong, and meant for indoor antenna only...
Can use for outdoor antenna too?

Last night I checked and found that the myFreeview watermark is gone from all rtm's non-test channels. It is still present on all other channels.

I faced this when really heavy rain with my DIY indoor antenna where one of the MUX will lose signal. Now okay already after I shifted the antenna to another position.

by right the watermark should be removed totally since we are already 100% in the digital broadcast. donno why they keep it as "test"
