Hello,
I am new to these forums and am really struggling to find an answer to my problem.
I use VDR on the raspberry pi. ( front and backend)
I am in the UK and use a usb tuner stick for the Freeview channels
It works great , but recently I bought a new dvb t2 tuner stick ( Geniatech t230 DVBT2 usb tuner ) and w-scan( or is it VDR? ) will not find dvb t 2 channels.
It finds dvbt fine and works fine- but no dVbt 2?
Other PVR software for the Pi ( tvheadend) finds the dvbt 2 channels easily.
A question on the openelec forum raised this explanation as a possible answer- can anybody shed any light on this??
There has been a change to DVB-T2 support recently, and newer drivers use the new model, as does TV Headend. It could be that VDR hasn't been updated to use the new model yet?
Older drivers (like the PCTV 290e) would tune to both a DVB-T and a DVB-T2 mux with the same tuning instruction (effectively if a DVB-T tune didn't work they'd try a DVB-T2 tune - effectively ignoring some of the demodulation parameters), possibly because there wasn't, then, a standard for sending T2 demod parameters to frontends.
The Linux APIs now include proper T2 tuning support, so newer drivers (I think the 292e, and some of the Geniatech/August dongles) use the new API, so need to be specifically told to tune in T2 mode rather than T mode.TV Headend was modified to add support for this new T2 model (probably because it's devs are based in Sweden and the UK which both have a lot of T2 stuff)
It may be that VDR doesn't yet have these changes made? Certainly on the VDR build in the OE 5.0.1 x86 builds I don't get a T2 tuning option (which I'd expect) for a single frequency scan. (VDR appears to be developed mainly in Germany, where T2 isn't yet broadcast.)
I've also found that VDR doesn't appear to support the UK Huffman compressed Freeview HD EPG information (though it does support Freesat - which uses the same compression, but with differently flagged packets - as Freesat has to work side-by-side with Sky's EPG) - so you will have to use XMLTV to get EPG data for the HD channels on Freeview in VDR ?
Buggy as TV Headend is, it still supports UK DVB-T/T2 stuff better than VDR in my experience.
Many thanks
