[GEM-dev] [pix_video] not working with usbtv driver/Easycap capture card

[Peter Venus]

Hello!

as for the easycap capturecards, i worked with a couple of those recently:
there are general problems with some chipsets, especially with those 
using the usbtv drivers.
when i tried to work with those in september, there was just a 
experimental linux driver available, which i didnt manage to get working 
in linux in general, not just pd.
so, if you have them working in cheese etc, aou are already more 
successful then i was.
my suggestion would be to get cards, that rely on the stk1160 driver, 
since they work perfect(i had 8 running at the same time)

i did some research on which cards are made with the original "easycap" 
chipset", and found, that [1] uses it. all the others, which go for the 
same 20eruros or so, i tested already used the usbtv-chipset/driver.
