This topic has been covered a few times there are a good few threads in the DVB chat section similar to this one, have a read through them and see if any of the information contained in them assists you.
I‘ve always been tempted to try it myself but it looks like to much of a steep learning curve for an OAP :)

Thread '4:2:2 on PC'

Depends on the mental acuity of the OAP, a sofa dweller with pipe 'n slippers got less chance than others.

Nowt to it really:

1. Get a cheapo DVB card such as TBS and install it in a PC. I prefer an internal card rather than an external USB device.
2. Install EBSPro freeware on the PC and use it to scan the feeds
3. Stream 4:2:2 feeds from EBS Pro to VLC

Job done, go back to sofa and light up the pipe...

4:2:2 is not any additional scrambling system or codec, it is color or chroma subsampling (so its about "some" chroma and luma values but its "extensive science"), so there is no special or specified card that "opens" or "decrypts" 4:2:2. PC SAT Card is only a tuner, a receiver, and viewing 4:2:2 feeds on a PC is enabled by the OS and player(vlc,mpc).
Even without a PC card, you can watch 4:2:2 feeds on PC if you stream signal from E2 or any other Linux box that supports stream to PC.
The PC SAT card card only receive the signal and everything else depends on the PC (player, CPU, GPU).

I suggest you about feeds to use EBSpro and VLC, because vlc not use anything from third party codec, but have and use than own internal libraries.
So vlc plays 4:2:2 as well as 4:2:0

With each PC SAT Card you will be able to watch 4:2:2 because that "work is done" by the OS and the player on the PC .
When buying a card, you should pay attention to whether it supports the blindscan option, provided that you are also interested in searching and finding feeds.

You could consider a TBS6902 DVB card for internal use in a PC, they are reasonable and work OK with blind scan in EBSPro.
For software, all you need is EBSPro and VLC, both freeware.

If you are OK with a used TBS card there are often some on eBay at a decent saving compared to buying new.
Older models such as TBS6982 are decent.

Both ProgDVB and DVBDream will scan and provide pictures of 4:2:2 feeds.
Personally I prefer EBSPro to scan then send from there to VLC, it is stable and reliable.

I'm not explicitly saying that you don't need PC SAT cards, but I just gave an example or an option that you can watch without a card. I worked like that for years because I didn't have a card, but of course it's more practical with a card,

Depends if latency is a factor.
If latency is a factor and you use the feed for betting you gonna get raped if you use the incorrect process.

EBSPro will scan in the feeds then output a selected feed directly to VLC.
The default install of VLC includes its own library of codecs and they are quite good.

There is plenty of info on this forum about viewing 4:2:2 feeds, it has been covered in depth previously several times.

NO, VU+zero does not support blind scan, but here we are talking about the stream from the receiver to the PC and wathcing 422 and not about the blind scan option!

EDIT:You edited post and here is answer: just manualy put the freq , polarisation and SR. So Yes manualy because Vu+ Zero dont support blind scan.

If the OP chooses to use a Vu+ Zero to stream from the webif they will need to source the feed parameters elsewhere in order to manually scan it into the Vu+
This is easy enough to do provided it is published on the forum or the OP has other blind scanning options.

If buying a new E2 receiver they might be better getting something like an Octagon SF8008 which does have blind scan capability and can stream from it's webif.
Until the OP confirms if latency is a factor or not then the best option for them is not clear.

My friend, you miss the point here I dont want to go to OT:
It is obvious that the title of the topic is how to "viewing 4:2:2 feeds", and I inform topic author, in addition to the PC Sat card, that he can watch 422 on a PC with a receiver. Nowhere did I tell him that he should buy a E2 box and not a card and there is a chance that he might already have an E2 box, so he can start watching right away.
So he doesn't write that he wants to be a feed hunter, but how to watch feeds, and I think that's a big difference.
That's why I don't understand why you quote almost every my post. I don't mind and I have nothing against it, but I don't really understand the point!

Hi Moonbase,
Great info and thanks for providing. If there was a usb tbs you could recommend. I’m keen to try this and the easy option is through a USB option.

I am not up to speed on the TBS USB devices, the only one I have used personally is the TBS5925 which is an older model.
It was replaced by the TBS5927 which included a small fan to cool it down.

If you go to the TBS website it should have the list of currently available DVB USB devices.

As the OP of the topic already has a Vu+ Zero and is now aware it can be used to stream 4:2:2 from its webif I will assume their question about viewing 4:2:2 feeds has been answered.
