See my post in the "New kernel 3.8.7" thread showing how to build an image with the 3.6 kernel:

But, as littlesat says, the issues with usb tuners and kernel 3.8.7 should be fixed now.

Thanks for the reply, reg.  I was under the impression that all DVB-T2 transmissions in the UK used a guard interval of 1/128.  Do you configure your tuner for a guard interval of 1/16 or "auto"?  In fact, is there any chance you could post your tuner status for a HD channel?  I.e. when receiving an HD channel, select "Menu/Information/Service/Tuner Status (Blue button)" and tell me what your box displays?  Thanks.

I'm quite certain I don't have a reception issue.

I've been trying to get my DM8000 to receive DVB-T2 using a PCTV290e with the latest OpenPLI 3.0 images without much success, I'm afraid. I also have a Philips internal DVB-T tuner in the box which I configure to "Nothing connected" in the tuner configuration setup, i.e. I haven't actually opened up the box and physically removed the internal DVB-T tuner.

The USB tuner works fine with DVB-T transmissions, but for DVB-T2, I find the USB tuner only very intermittently manages to perform a channel scan of the multiplex and (if a scan succeeds) never manages to tune to a DVB-T2 channel (always giving a "Tune failed" error).

Where I live (South of England) the Rowridge transmitter uses the following parameters for its DVB-T2 multiplex:
Centre frequency - 474167000Hz
Bandwidth - 8MHz
Constellation - QAM256
Code Rate 2/3
Guard Interval - 1/128
Transmission mode - 32K

There is no way currently to specify a guard interval of 1/128 and transmission mode of 32K, so I have no choice but to set these to Auto.

I'd be interested to know whether reg's and jakey's setups are still working OK for DVB-T2? Perhaps they could tell me which transmitter they are served by and I could check whether the transmission parameters are different. And pieteg, is there any chance that the ability to set guard interval of 1/128 and transmission mode of 32K could be added to image at some point?

Thanks, wavelet.

Use OpenPLi 2.1...

 
You could also try building your own image with the 3.6.0 kernel by checking out from the git repository the commit just before the kernel was changed to 3.8.7.

mkdir openpli-3.0
cd openpli-3.0
git clone git://git.code.sf.net/p/openpli/openpli-oe-core
cd openpli-oe-core
git checkout 34158b82fec83859839421d642e32ef3a644a3da
make -f Makefile MACHINE=etxx00
make image
