I am considering replacing my internal TV tuners with some network tuners instead.
I would be really grateful to know, from any one using them, whether they cause any problems in terms of traffic on your network.
I have a gigabit network and would ideally like to have two DVB-T2 and two DVB-S2 tuners.
Worst case scenario might be recording 4HD streams whilst streaming another 3HD streams to three clients.
Is this sort of set up likely to cause any problems?

You have some recordings already from your existing tuners. Do the math. But I know plenty of people do similar things, even on 100 m networks. You might like to consider using a separate network segment between your tuners and your server.

Where do you find a network DVB-S2 tuner? Or do you really mean USB-connected?

I have 3 HDHomeRun Prime units on my network. US cable streams are generally larger/higher bandwidth than DVB; in general a cable stream is about 12-18 Mbps, so 100Mbps connection is sufficient for 3-4 streams for a device onto the network.
My network is mostly gigabit wired, but my network tuners are limited to 100Mbps (because of hardware/firmware issues, not for network issues). I have no problems with 5 HD streams being recorded onto a NAS also on the GbE network.
As far as traffic causing issues with my network and congestion, the only time I have noticed problems is also when I am downloading torrents. Otherwise, there is no problem. Of course, your experience may differ, but I have had no problems with 7 HD streams recording/streaming to NAS and across to other devices in the past.

Only one stream per tuner?

The HDHomeRun tuners are not yet DVB-T2 certified. I know that Germany is about to get rid of DVB-T and go all in on DVB-T2 (including H.265), so I'm not sure how that affects the UK; but there are still some lingering issues. There's a thread over at the SiliconDust forums about this.

I've got a HDHomeRun dual tuner with a softcam and next to that two FloppyDTV tuners with an Alphacrypt CAM each.
DVBLink seems to be able to handle everything on my network just fine. Most HD streams are 3-4 mbps. Not an issue in my opinion.
In the long run I am looking to replace all tuners with one HDHomerun quad tuner. That way I can switch to a less power consuming HTPC as well.
Only issue I currently have is that Kodi every now and then has a slight stutter in live TV until I reboot the computer or put it to sleep and wake it again. No clue yet what causes it. If I select live TV on VLC or something else on the same machine there is no issue.
