[pvrusb2] B&W video problem...

[Helmut Toplitzer]

Have you tried some "non software" tests?

Temperature instability?
Mechanical shock?

On NTSC color info is coded and modulated on seperate
frequencies to keep backwards compatibility to B&W.
So they are normaly filtered out and amplified/decoded 
in a seperate way.

Maybe your tuner has got a problem with a cold soldering
point or a dieing electrolytic capacity?

Cold solderings are sometimes detectable by turning the device
upside down, capacity problems with ELKOs happen during time
and are also temperature sensitive.

Does this problem also happens on MS-W?

My 2c.

Helmut
