/dev/video0 exists. i can cat from it to mplayer resulting in snow. i can cat from it to the console, resulting in (haha) ascii snow. i can cat from it to an .mpg file, which plays back as snow. i have used ivtvctl to make sure i'm using ntsc, and tried using pitune to flip channels and inputs while cat'ing video to mplayer - more snow.
tvtime says "cannot open capture device /dev/video0" and spits this at the console:
videoinput: Card failed to allocate capture buffers
i tried this: echo 16384 > /proc/sys/vm/min_free_kbytes but it didn't help.
any related experiance, or suggestions would be appreciated. thx in advance
