Known Problems
==============
--------------
* The tuner for the flyvideos isn't detected automatically and the
default might not work for you depending on which version you have.
There is a tuner= insmod option to override the driver's default.
Card Variations:
================
----------------
Cards can use either of these two crystals (xtal):
- 32.11 MHz -> .audio_clock=0x187de7
- 24.576MHz -> .audio_clock=0x200000
(xtal * .audio_clock = 51539600)
- 32.11 MHz -> .audio_clock=0x187de7
- 24.576MHz -> .audio_clock=0x200000 (xtal * .audio_clock = 51539600)
Some details about 30/34/35:
- saa7130 - low-price chip, doesn't have mute, that is why all those
cards should have .mute field defined in their tuner structure.
