grabbing problem

[Alexey Matsishevsky <matcik@xxxxxxxxxxxxx>]

Hi!
I have few questions.
I try to create my program for grabbing and use Programming-FAQ in 
xawtv-3.54
What size VIDIOCGMBUF?
I do : printf("VIDIOCGMBUF=%d", VIDIOCGMBUF);
I take: VIDIOCGMBUF=-2138540524 - I don't understand it.
And next question: what is the error: VIDIOCMCAPTURE returned error 25???

Help me please.
matcik.
