Ideas for a new sat-setup IPTV, SAT-IP or VU+ kodi addon?

No expert on this but with a bit of googling you can find all your answers.

If your box is stalling all the time, give it a clear out, reflash a new image, delete unnecessary plugins and media plugins. Keep it barebones, your box will fly.

You can have 2 boxes, but use 1 satellite line. You can then use something like the remote channel stream converter plugin, to import your bouquets to another box.

As you only have 1 satelitte cable, you will only be able to watch channels on the same transponder at the same time.
If you want to watch different channels or record and watch a different channel you would need an lnb with at least 2 cable lines.

As for a central recording hub, you just need a nas drive on your network, and then you set up your recording to save to that.

For zapping speeds, you don't say whether you are using a paid line or other, but usually this is down to your provider, the speed of your box, the softcams software you are using. I suggest using oscam as your softcam software with a couple of lines. If using any other softcams probably best to give your config files a once over and remove unnecessary stuff like logging.

I am using a hybrid enigma2/android box at the moment and to be honest I find the android side of things annoying. I stick to enigma2 most of the time.

If you want to use your android boxes, probably best just to use for iptv, stick perfect player on them and get a couple of descent iptv lines.

Totally different to what you spec'd so far but this would be wife/family friendly for TV.

I'd suggest a Quad Satellite tuner receiver to use as main server. VU+ Duo2, Xtrend ET8500...

Then use say Single tuner E2 receivers with OpenViX. Install the plugin 'Channels Importer'. Channels importer will import the channels from main receivers and EPG data.

You can then setup network mounts on the client boxes to the main receiver and mount the main receiver hard drive. You'll then be able to watch recordings on the client boxes.

ET8500 with four Satellite tuners = £140.90 or VU+ Duo2 = £304.00.

2x Edision OS Nino = £66.00 each. Or higher spec Formuler F4 Turbo = £69.00 each when buying two.

Kiddac - which hybrid box are you using if you don't mind me asking?

Dinobot 4k. Its a fast box, but it has its problems. I will be writing my experiences with it in dinobot 4k section very shortly.
