Look careful. video0 is a character device, video1 too (you see that
"c" at the beginning of the line, where usually is nothing or a "d"
like directory? This is the flag for a character device). but
video16 is a simple file - and this is wrong.
try the following: remove /dev/video16 (this is just a file, I think
with the mpeg-data in it) and type the following:
mknod /dev/video16 c 81 16
This should create the character device /dev/video16. After that,
retry your tests.
