Too bad. I will check anyway the export cost, just to check if it makes sense. BTW, did you have the chance to look at the logs I attached, just to figure out if something is wrong or something can be debugged at my side?

In summary, my problem is that I started getting signal/locking errors in VDR if I tuned one frontend, and VDR scanned EIT/EPG using the second tuner in the background; by disabling the second tuner it works. I managed to reproduce the problem by simply using dvbzap/dvbv5-zap in command line. And it suddenly started failing on the 1st of Dec 2014 (after a frequency change in DVB-T in Spain). I tested different Ubuntu distros wich previously worked, but I can't manage to make it work now using the default kernel included in the Ubuntu ISO image that I had installed. I am testing now with Ubuntu 15.04 nightly, kernel 3.18, in a separate hw platform. I also tested with MythTV and TVHedaend, but as I managed to reproduce it with the dvb command line tools, I don't test any GUI anymore. I've also tested it in Windows 7, and it works tuning both tuners simultaneously, so I discarded a hardware problem. I've also tested with the latest git from the v4l repo by following this guide (basic approach): http://linuxtv.org/wiki/index.php/How_to_Obtain,_Build_and_Install_V4L- DVB_Device_Drivers with the same result. My guess is that something in the cx23885 driver does not like the current DVB-T signal in Spain. Is it possible that something similar happened where you live? The problem is that I don't know how to proceed to debug the issue, so any advice is welcome.

Thanks Steve. If sending it really helps you in your development, I will gladly pay for the postage forth and back if you live in Europe. When my recently purchased HVR-2200 is stable in my PVR (I could still use the Terratec disabling one tuner), I will consider donating the Terratec.

I consider the current driver broken until the feedback on the mailing list dies down. I'm reluctant to work on the driver while its considered unstable. If you want to send me a Terratec card then I'll try to fund an hour to investigate in the coming weeks.

Thank you for your comments, James. I'm sure it's not a hw fault because mine
works in Windows perfectly, and both tuners used independently also worked in
Linux.

I'm having problems using both tuners in a dual tuner card (Terratec
Cinergy T
PCIe Dual), also based on cx23885, but it uses different frontends/tuners
than yours.
I'm pretty sure mine was an actual hardware fault. At first it worked
perfectly. Then after a bit the server would occasionally lock up hard or
reboot, then more often, then every time. I spent ages thinking it was a
driver problem and did all sorts of traces etc and found nothing. In the end
I just got mythtv to not use the second tuner (or the first tuner - as long
as only one was used it was fine).
Then about a month ago it started locking up again occasionally, then more
often, then every time, only using the one tuner. Strange though that if it
booted up without locking up it would be okay.
I bought a usb tuner and haven't used the cx23885 card since.
I will be seeking a replacement under warranty though, as the signal quality
is quite a bit better.
Good luck in your quest though!

My guess is that something in the cx23885 driver does not like the current DVB-T signal in Spain. Is it possible that something similar happened where you live? The problem is that I don't know how to proceed to debug the issue, so any advice is welcome.

Thank you for taking your time to answer. Yes, I tried different kernels focusing con Ubuntu distro. I don't remember the exact kernel version, but at least those included by default in the Ubuntu 12.04 lts and 14.04 lts ISO image, which worked for me.

I'm not even sure why I read this list, but can you determine if the problem is associated with a particular kernel version? i.e. if it works on x.y.z but fails on x.y.(z+1) you have a starting point. If you use the word regression and a kernel version number you might get more attention - but I'm only guessing.

I have a VDR based PVR at home, installed over an Ubuntu 14.04 LTS. Everything was working perfectly, until beginning of December. It seems to me that something changed that broke my PVR pretty bad. The problem is the following: tuning (zap) both tuners (it's not needed that both are tuned simultaneously, only one after the other, in no particular order) makes the tuners to enter an state where they can't lock the signal anymore. Facts: - My TV card is a Cinergy T PCIe Dual from Terratec (http://www.linuxtv.org/wiki/index.php/TerraTec_Cinergy_T_PCIe_dual). - The problem arose in the form of frontend x/0 timed out while tuning to channel ... in /var/log/syslog. It happened when both tuners are active, during EPG scan. The problem does not happen if VDR is run with -D parameter to limit the number of frontends enabled. Disabling the EPG scan with both frontends enabled minimizes the problem, but doesn't
