Hi,
I just got an antenna mounted at the top of the building for DVB-T reception. I'm even very close to the transmitter tower, and the system was made by a professional, the signal is great!
I'm already running VDR as a backend with a DVB-S2 card for a long time and it is rock solid and stable.
At the moment I have a cheap Chinese off the eBay tuner for DVB-T. Basically it works, no problems at all, except that it uses mcx connection, so an UF to MCX cable needs to be inserted, and I guess I loose a lot of signal strength on that conversion, as it is a thick cable, but I can't confirm that, no ways to test.
The tuner is identified as:

So it is an ITE device, and IT913x bx. I'm on kernel 3.19.0-28-generic #30~14.04.1-Ubuntu, tuner is found without need of media_build.
The only problem I have is with the HD channels, all the SD channels are working excellent. The HD channels are sometimes working good, there are only occasional pixelations on the screen, however, sometimes the video gets corrupted, and it "brakes/falls apart" and becomes green, and garbage on the screen. Switching to SD channel is perfect. After a restart, it usually works. I get full of this in VDR log:
Sep 17 08:48:00 serverpc vdr: [3788] frontend 0/0 lost lock on channel 153 (M1 HD), tp 722
Sep 17 08:48:02 serverpc vdr: [3788] frontend 0/0 timed out while tuning to channel 153 (M1 HD), tp 722
Sep 17 08:48:03 serverpc vdr: [3788] frontend 0/0 regained lock on channel 153 (M1 HD), tp 722
Sep 17 08:48:06 serverpc vdr: [3788] frontend 0/0 lost lock on channel 153 (M1 HD), tp 722
Sep 17 08:48:06 serverpc vdr: [3788] frontend 0/0 regained lock on channel 153 (M1 HD), tp 722
Sep 17 08:48:06 serverpc vdr: [3788] frontend 0/0 lost lock on channel 153 (M1 HD), tp 722
Why could it be, any ideas?
On the other hand, could you recommend me some cheap USB DVB-T (single) tuners that work fine without any problems on Ubuntu kernel 3.19 and onwards, and VDR?
Please list some specific names.
Thanks!
