Hey all!

It’s been a while since this was last talked about, basically I’ve moved so I’m taking this opportunity to build out a new sat setup and I want to be able to decode 4:2:2. A lot of different solutions are suggested, but nothing which is repeatedly recommended. What is the best way to do this?

Thank you for the help in advance!

Nothing has changed. It is best to use a satellite card and a codec that can process 4:2:2.
Or streaming from the receiver to a PC or mobile if it supports it.
Professional receivers whose HW can process 4:2:2 into VIDEO output, ASI output, IP output are still very expensive.

I have one for sale if you want, but not cheap unfortunately.

Well, I have two friends in other forums who say yes.one of them posts them on a well-known feed page

The GTMedia Combo cannot play consistent smooth viewable video, it will play it but generally it becomes jerky.
To see what the content is for a 4:2:2 feed the GTMedia Combo does a good job. However, as a consistently smooth video player of 4:2:2 it is useless.

If you want to view smooth good quality 4:2:2 video your only options are a DVB card in a PC or a professional grade receiver such as an RX8200 or stream to VLC from a receiver.
A possible issue with streaming to VLC from a receiver is latency.

This question has been asked quite a few times and nothing has changed, the answer remains the same, DVB Card in a PC or a professional grade receiver or a VLC stream from a receiver.
There are currently no consumer grade receivers that will directly play smooth viewable 4:2:2 video in DVB-S2 format. Years ago the Quali TV receivers would play 4:2:2 but it was only in DVB-S format.

Nothing has changed and will not change in the near future because 4:2:2 color subsampling is not a standard but 4:2:0, so device manufacturers will not "insert" support.
4:2:2 is no codec, no additional encryption, so there is no "decoding" or "opening", and it is not "opened" by the TBS PC Sat cards, but viewing is made possible by Windows OS and Player (Vlc, Mpc...).
So there won't be any commercial receivers that will support 4:2:2 "on the fly" or in realtime, without "additional internal players" that actually do an internal stream with catastrophically bad picture.

"latency issue" don't take it as a problem when streaming either from an receiver to a PC, since the delay is negligible and of course - there are some of us who have this about feeds and SAT TV as a hobby and we are not interested in bookmakers and betting, so the problem of delay is not a problem.

So, nothing has changed since the time when the Azbox models of the company Opensat were the only receivers in real time, without loss of image quality and without an internal auxiliary player and streams, which enabled watching 4:2:2 but only and exclusively MPEG 2, while MPEG 4 could not. That company no longer exists, and whether it is related - anything is possible.

After all, everything related to 4:2:2 is covered in several same or simular topics and I quickly found some so you could read this:

I believe that the only way to view 4:2:2 feeds WITHOUT any issue or limitation is a professional receiver.
Yes you can stream to your computer but a little bit of skill is needed and more devices are involved.
Using such Ericson boxes or similar... well, you switch on and watch. Very simple.
The unique problem is that these receivers are not cheap and not easy to find and buy.

is there a option to input the key on the pro boxes or how does it work if there not tied to broadcasters.

Thank you all who have been able to chip in and explain what I need to look at.

What I’m taking away from this is that the GTMedia boxes can be hit and miss, but ultimately futile or pointless. My best methods would either be to buy a professional receiver or use a satellite card.

It’s likely I’ll lean to the latter as the RX8200 is expensive for what I actually need to do. What do you recommend in terms of GPU for PCs to procees? Many swear by NVIDIA or AMD Radeon Pro, so interested to know what you think.

Appreciate the time of everyone who has talked through this - and I will read the tagged threads in the next hour or so.

I find Media Player Classic best for 4.2.2 stream's from a satbox as it use's Lav codec it gives the best playback smooth and glitch free in my opinion VLC can sometimes glitch a little bit or just stop the stream after a hour or so I always recommend a good spec satbox and Pc with a GPU for 4.2.2 stream's I have 2 desktop PCs and a laptop all play 4.2.2 stream's excellently spec of both PCs and laptop are below you will always find a DVB Card in a PC the best opinion for 4.2.2 playback if you look on eBay you can pickup a second hand tbs card cheap I got a TBS6902 for £35 last year only thing is it did not come with the power cable so I just made one but its still better then over £100 for a new one
