Plenty of demuxers. So your issue is elsewhere, I have no problem opening 14 VLC streams on my box.
Perhaps the SoC has other limitations, the Galaxy uses a BCM7252S, which is a SoC developed for DOCSIS and Cable implementations. Or there are network limitations.
Maybe others can check, there are more boxes with that SoC, for example the GigaBlue UHD UE 4K.

That is what the driver says the SoC supports, yes.
I don't have the datasheet of the 7252s handy to verify that, sometimes drivers tend to lie, or they reserve demuxes for USB or SAT-IP tuners, etc. so not all of them are available for internal tuners.
I checked on a VU+ Solo 4K with a DVB-S2 FBC tuner, which has a better SoC, but also reports 15 demuxers.
I know some readers here have a Gigablue UHD UE 4K, a Xsarius Galaxy 4K, a VU+ Uno 4K, a VU+ Uno 4K SE, an Axas E4 HD, or even a DM900 or DM920.
They all use the same SoC, so if someone can test the number of streams that will open? No need for FBC, just pick a transponder with 14+ (preferably FTA) channels...

On Vix/ATV, there is bug and you cannot record that number. You get spurious timer conflict messages.
I have never tried maximum number of recordings with unicable LNB on a receiver with FBC tuners.

Hi,
with unicable you can use up to 8 transponder with the 8 demuxer. With universal LNB you can use 8 transponder out of 2 bands (high/low/horz/vert). Im not sure about streaming but for recording around 30 is possible if you record 3-4 channel from the same transponder.
