I’ve had a few attempts with these - they don’t seem to be that sensitive (i.e. you need a better signal with them than other DVB-T2 tuners). I also found that they had issues at some frequencies (I’m UK Crystal Palace)
They were OK - and very cheap - but the Win TV Dual HD seemed more robust with my aerial feed. (Though I’ve lost COM7 and COM8 with the move to UK-wide SFNs that have taken them out-of-band for a legacy Crystal Palace aerial)
Play TV is a dual tuner, but DVB-T only - so it won’t get HD channels in the UK where DVB-T2 is used for HD (Th Play TV will get HD in places like France, Norway, New Zealand, Aus where HD is DVB-T not DVB-T2)
The Xbox One tuner is a single tuner, but DVB-T2, so will get Freeview HD in the UK.
@vlade if you are still struggling - no need to build TVH on an N2 - it’s installable in the Services area of the CoreElec Add Ons Repo.
I was looking for 4.3, to see whether it worked any better. The issue with Hauppage’s DualTV seems to be that once CE goes to suspend, it somehow loses the connection and the ability to re-tune.
Hauppauge Dual TV (dual tuner, T and T2 support): - works only of the micro USB2 on the front, doesn’t work with USB3 on the back. Stops working on suspend, requires reboot. Deadly if you want your box to suspend and wake up for recording.
XBOX Tuner (single tuner, T and T2 support)- works ok with the back USB3 ports, but has problem if your DVB-T2 uses dynamic PMT tables, in which case you may get mostly just sound, and often nothing (reportedly it works with Xbox in such a situation).
Hauppage seems to be more choppy on T2 channels than Xbox.
Other options for reliable working are SiliconDust HD-HomeRun Dual or Quad DVB-T/T2 network tuners. That removes all driver issues from your set-up. I’ve had a Dual HDHR running into a small ODroid HC1 + 2.5" HDD running OpenMediaVault and TV Headend for a while now - it “just works”, whilst others use their NASs to run TV Headend with the HDHR as their tuner solution. The HC1 draws such little current I leave it always on though.
Separating TV Headend backend from your Kodi front end does make life a lot easier - particularly if you have multiple Kodi front ends (as I do)
For me, the best and cheapest is Microsoft Xbox One Digital TV Tuner (~10/11€). It works with Media Build drivers.
Note: I had a problem with a local TV channel that changed the frequency, but I wrote an email requesting the revision of the transmission parameters and on the third day everything was solved. The tuner was not guilty.
I’m not sure you’ll find any FBC-capable USB tuners. FBC is really only available in dedicated satellite receivers like Enigma devices, Sky Q etc.
I’ve only ever seen single-tuner DVB-S/S2 (S2x in some cases) USB tuners for sale - usually limited to Universal-style LNBs with basic Diseqc switching. (Some may also support a single tuner using Unicable or Unicable II rather than Universal LNBs)
There MAY be a few FBC PCI-E cards for use in PCs - as there are dual, quad and octo PCI-E tuners for sale - but they are not cheap, and would need to be part of a PC TVHeadend back-end.
SAT>IP Quad Tuner network solutions are available too. These are not FBC - but some have Unicable II support for single cable working with multiple tuners - though this may required third party firmware like Sat Axe.
I can confirm this behaviour with GT-King Pro too. Tested with CE 220.127.116.11, WinTV-dualHD runs only in usb2otg port and stops working on resume. Needs reboot or unplug/replug.
But it seems not to be specific only to the Hauppauge - just tested it with AVerTV Volar Black HD tv tuner (af9015 chipset, DVB-T only) and even though it works in usb3 ports as well as in usb2otg, the problem with suspend/resume stopping to work occurs too.
It helps to set “USB Power” to ON in Inject BL301 options - both WinTV-dualHD and VolarBlackHD tuners then continue to work after resume.Not a very nice workaround, but maybe it helps to narrow down the cause?
