In case of the em28xx each device has its own configuration and there
was no such entry for NTSC or SECAM for his device.
Also it's up to the videodecoder module how the format will be handled.


Anything i can do about it? I have no problems patching and rebuilding
till it works.


I added NTSC to the supported format list of the em28xx, maybe with
some luck it will work otherwise we have to go another way.

Those channels originate from my cable provider, those channels are not
part of official air distribution so the provider opted to broadcast them
in PAL (for whatever reason), the rest map 1:1 to the ones from the air
(and hence are SECAM). As for which sub-standard.. I don't really know
xawtv (bttv(avermedia) + v4l1) on my other machine were simply told that
it's PAL and everything was fine.

Anything i can do to difure out the particular PAL brand?


you can have a look at em28xx-cards.c/EM2820_BOARD_PINNACLE_USB_2 and
extend the input array if needed. I haven't added secam there yet.
I don't remember that anyone ever requested NTSC for that device, and
I thought it supports PAL only.
