Re: [possible BUG, cx23885] Dual tuner TV card, works using one tuner only, doesn't work if both tuners are used
Tested with a couple of DVBSky T982 adapters against latest media master. No problems detected. Moreover: even with earlier versions of the media tree (starting with the version in witch support for DVBSky t982 was added), I never encountered any problems. Regards, Tycho.

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? I'm not expert in V4L stuff, but I am a programmer and could test things by myself if some advice or guidance is provided. Maybe there is a DVB/V4L programming tutorial somewhere?

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.

Re: [possible BUG, cx23885] Dual tuner TV card, works using one tuner only, doesn't work if both tuners are used
While I am the maintainer of the cx23885 driver, its currently undergoing a significant amount of churn related to Han's recent VB2 and other changes. 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.

RE: [possible BUG, cx23885] Dual tuner TV card, works using one tuner only, doesn't work if both tuners are used
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.

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! James
RE: [possible BUG, cx23885] Dual tuner TV card, works using one tuner only, doesn't work if both tuners are used
Hi, James.
After searching for somebody posting some issues similar to mine, I think this
one you posted to the mailing list can be related:
https://www.mail-archive.com/linux-media%40vger.kernel.org/msg80078.html
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.
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.

Hi, blind Pete.
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. The latest Ubuntu
version I tested was the nightly 15.04 from the 7th of January.
