Good problem report should include

0. Note that you are using V4L CVS.

1. Name of card

2. lspci -vn

3. Dmesg log of module tuning and probing. It also nice to add audio_debug options to modules, tuner_debug option to tuner module and debug option to tda9887

4. Television standard for your country.

5. Exact sequence of actions that causes your problem.

6. Generally, "your problem" is a combination of an app and a driver. Also generally, the problem only exists in one of those, but it isn't always easy to tell where. A big help is to check each part with various tools in the Test_Suite.
