I'm using TM Unify 30MBPS

You need to have a card which can take video feed, though i think with Astro it's difficult to get the direct feed, cuz Astro channels depending on decoder and smart card... so a normal TV tuner card may not work for Astro feed.

Bro you PM me for details and let's connect. I don't mind building a full setup depending on your choices will cost at most around RM350-420

Yes they do. Whole keyboard works without issue. But some keys on front/media side are not recognizable but rest works and can be configured to perform any action.

Sure bro we can catch up anytime ...

Ok i will try to test, it's just i don't have any media on USB as i'm using a purpose build NAS in my setup... so only that i need to copy movies to some USB and test and cuz I'm currently building 3 more RPI 2/KODI setups two for the forumers from here, who requested me to build for them so may need some time to test this setup.

Which one?

RPI2 does support Digital Audio over HDMI and does support Passthrough for DD & DTS. However it doesn't support HD-Audio. I have tested it by connecting with me AVR and it works perfectly fine.

So I have tested 2 remotes with RPI 2, Mele F10 Pro Deluxe and Minx Wireless Remote. I found Mele F10 to be better and it works fine with Kodi/OpenElec/OSMC.
There's only one key which doesn't work if you using on RPI2 which is the menu key but rest all work out of the box and can be reconfigured to assign any action.
If you use these remotes with KODI/OE on an intel PC then even Menu key works fine.
So those who are looking for a small/dual job remote/keyboard for KODI/OE/OSMC on RPI or Intel PC can sure use Mele F10 Pro Deluxe as a good option.
I didn't try Rii remote which i also suggested earlier cuz of the price difference between 2, Mele F10 Pro is way much cheaper than Rii (At least to me as i did a bulk deal with the vendor and got a good price )

Bro now i don't think so i will test the RII, i thought about it, even if RII is better i don't think so it's worth to pay the extra difference if i compare price of both. In the seller interest i won't disclose the price at which i got Mele but let's just say a difference of RM40++ is not really worth spending what extra RII could offer and as i said on RPI only 1 button not working and on Intel Platform even that one is working...
So you tell me would you really pay RM40+++ extra for RII??? Especially when whole premise of talking about RPI is building stuff cheaper

Bro give me a day or two and i will test and update for last few days i have been busy in building the new RPIs for community and cuz those are using OSMC so i didn't check on new KODI release

There's some problem with RTM 1 & 2 feed, even on IPTVxtra they are not working will look into this. I have tried a lot to find Disney Jr & XD but still couldn't find a good source... Will keep searching.

Let me understand this when you say HT means (Home Theatre is those HITBs, Home Theatre in a box?) and not those with AVR and Separate Speakers??? Cuz from what you stated this is what i think is the case...
What most of us are doing is connecting our RPI to AVR through HDMI and then AVR to TV and that's how you get more than 2 channel sound.

Well this has been discussed in detail in earlier post, if you just go back few pages and look for my posts you will find i have explained in quite detail PROS/CONS of Android boxes and RPI2.
In a nutshell for Kodi RPI2 is far better than any Android Box but it's only if using Kodi is your only requirement.

This is the problem with Android boxes and so i have been saying i don't like to use Android boxes when it comes to KODI.

You need to check the Video Acceleration settings, also under Video->Playback->Adjust display refresh rate to match video... change that to "Off" and Video->Playback->Sync playback to display to "On" or "check"

This may help you with stutter.
BTW are you using Audio Passthrough?

I won't suggest to play with "Adjust display refresh rate" setting first, keep it to "off", only change "Sync Playback" to "On" / "Check", this also if you feel/face stuttering issue, I have "Sync Playback" to "On" on my FireTV and other devices cuz on my FireTV i was experiencing stuttering but this doesn't effect my Audio Passthrough and there's no sync problem i'm facing.
You need to check and confirm your TV supported Hz and also your AVR supported Hz, only then play with "Adjust display refresh" settings.

For further explanation read below.

"Adjust Display Refresh Rate" will switch the output refresh rate when playing back a file to the best refresh rate that is supported by the display AND the hardware Kodi is running on (as reported by EDID) If you don't select this option then you output at a fixed display refresh rate, which is usually set in Settings->System->Video Output. This setting allows Kodi to change the frame rate of the video output fed to the display, to ensure the best refresh rate is selected.

So if you have a display that supports 50Hz and 60Hz content, 50Hz content will be output at 50Hz and 60Hz content at 60Hz, however 24Hz will be output at 60Hz with 3:2 (ignoring 1000/1001 refresh rates (*))
If you have a display that supports 24Hz, 50Hz and 60Hz content, then 24Hz will be output at 24H, 50Hz at 50Hz and 60Hz at 60Hz. This is great if you have a display and hardware that copes with everything flawlessly.

"Sync Playback to Display" is different. It alters the playback speed so that it matches the display refresh rate (which could be fixed or could be variable if you have also selected Adjust Display Refresh Rate)

Why is this useful?

Say you have a 50Hz display but 24p content. 24p content will look horrible if you play at 50Hz, but if you Sync Playback to Display it will play the 24Hz back at 25Hz which will look much nicer at 50Hz. (Even if you have a display that syncs to 60Hz and could watch 24p material with 3:2 - which is nicer - you may still chose to watch at 50Hz with speed up and 2:2 to avoid the 3:2 judder. I sometimes do.)

Also - if you have a Kodi platform that can't cope with 23.976Hz output, but it can cope with 24.000Hz, you would normally get a repeated frame every 40" or so to keep stuff in sync. However if you also select Sync Playback to Display then Kodi will slow speed up the 23.976Hz content to 24.000Hz - so no repeated frames (and thus no stutter) but you then have to sort the audio sync out (either by resampling or by dupe/dropping)

Install opensubtitle add-on from the subtitle add-ons then if a movie won't have a subtitle you will be able to download on the fly while watching movie.
If you want the subtitle to be downloaded automatically at the start of a movie then also install "Autosub" add-on.

Bro, Android boxes are kind of all the same using similar kind of chipsets and most of the seller sell their Android boxes for Kodi (At least that's how they always advertise) If your only use is to run Kodi to watch Movies, Dramas and Live channels then i would suggest better go with RPI2 as that's more stable and performance is also better.

Bro RPI 2 is more recommended for a pure use of Kodi, as if you only want to use the device for Kodi then better go with RPI2, it's the best solution for that price.
Now as far as your queries are concerned:
1. You can go to youtube or Kodi/OpenElec/OSMC websites to see the interface.... as RPI2 will straight boot into this OS/Environment... which also highly customisable to your liking
2. 10MB will be good
3. Yes you can watch TV/Movies/Dramas online or offline with Kodi and as i mentioned earlier it boots directly into that interface.
4. The maximum no of add-ons on any platform are available with Kodi so this is not an issue
5. Yes it can connect to your local network or internet to search and play contents
6. Yes you can setup remote/keyboard/mouse
7. there are live TV add-ons available
8. Yes there's a app available to control Kodi from your iphone/android device name is Kori... which is available in play store.

The device is even more simple and straight forward than any Android device as in an Android device first you have to boot in Android and then run Kodi... Also it's very easy to build and setup... and if you like there are people her who will be willing to help you (I have build 4 devices this week for few forumers here )
So if you can't do it yourself ... you can always find a soul willing to help you Enjoy

I'm using "Audio Passthrough", "H/W Acceleration" & "Sync" checked as a default setting on all my devices. and As two of my devices support HD-Audio so i have enbled all the HD-Audio formats for Passthrough as those are supported by my AV as well.
