Solved!

I had to manually configure the bandwidth in tvh for the DVB-T2 muxes (8Mhz for UK Freeview).

If it was set to AUTO, scanning and tuning always failed. Even when the other parameters were set correctly (Delivery mode, Frequency, Constellation, Transmission mode, Guard interval, FEC).

As soon as I set bandwidth to 8Mhz on the DVB-T2 muxes, scanning, tuning and EPG collection work perfectly. Wonderful!

Thank you to crazycat and edit4ever for helping me to figure this out. I hope this can be useful info for anyone else struggling with the same situation.

dvb-t2 mux must be assigned to dvb-t logical frontend in tvh. Need set delivery system as dvb-t2 for certain mux, because dvb-t/t2 autodetect not supported.

Thanks crazycat.

So it sounds like it should work, and I have tvh configured as you suggest but tuning / scanning still fails. As as sanity check I disabled tvh, cold booted the system and ran w_scan but although it appears to detect the DVB-T2 muxes, it also reports a similar tuning failure.

I have a good signal - my TV can tune the DVB-T2 muxes no problem.

Hi all.

I have been running two of these since LE 7.x and am now on LE 8.02 Generic.x86_64. I am on a DVB-T / DVB-T2 network in the UK. I definitely have the UK version of this adapter (clearly shown on the original packaging).

For me, both tuners have worked fine for DVB-T since (I think) LE8.0, but I do not have any support for DVB-T2 (i.e HD). I have read this thread carefully but cannot find any mention of whether DVB-T2 is expected to work with this hardware on LE 8.02 or not? People seem to be suggesting it does, but nobody has made any clear statement about it either way?

Also, in tvheadend I see three tuners for each adapter, one DVB-T, one DVB-C and one ATSC-C - which can't be right as my version of the hardware does not support ATSC. See attached pic, is this what everyone else is seeing?

Do I just need to be patient and wait for support for this hardware to improve in LE or is my system misbehaving or misconfigured.

I started with a clean install of LE8 and have updated to 8.01 & 8.02 via the standard built-in update procedure. Other than that my system is completely stock.

Thanks for any clues.
