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

[Steven Toth <stoth@kernellabs.com>]

I didn't see anything obvious in the logs :(

Please don't send the hardware to the US unless you're willing to
leave it with me permanently, I don't work on hardware for free if I
don't get to keep the final hardware. I hope you understand.

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?
