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

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.

Hi, As I faced problems with my Terratec Cinergy T PCIe Dual and was unable to solve it (yet), I recently purchased a used Hauppauge HVR-2200 PCIe dual tuner. I immediately ran into problems with the HVR-2200 as well, perfectly described here: http://whirlpool.net.au/wiki/n54l_all_in_one (scroll down or search saa7164_cmd_send() No free sequences) Basically, it starts working but after a while I get an Event timed out message and several i2c errors and VDR shuts down (some hours after reboot). As the web page mentions, I tested downgrading the PCIe bandwith from GEN2 to GEN1 without success. But after playing with different BIOS options, what did the trick was limiting the power-saving C-states. If I select C7 as the maximum C-state, the card fails as described. After limiting the maximum C-state to C6, it has been working for a whole weekend. The HVR-2200 was also tested in a GA-H67MA-UD2H-B3 board with an G1610 Celeron, working without problems (although maximum C-state setup was not checked). Probably the error is present in other saa7164 boards. My VDR server is based on BayTrail J1900 (Asrock Q1900M). PS: I'm still waiting for advice regarding my Cinergy T/cx23885 problems and debugging.
