Francesco,

I've also had recent problems with grab image creation.  I didn't really 
have time to debug the source of the problem (updates of vdr, 
ImageMagick, kernel...).

I choose a "brute force" work-around using TVTIME (distributed with 
Fedora Core):

# run tvtime-command to create a png image

tvtime-command SCREENSHOT "bg.png"
sleep 1

# use ImageMagick to covert image to jpeg

convert ~/bg.png ~/bg.jpeg

# move bg.jpeg from home directory to directly specified on command 
line, i.e. .

mv ~/bg.jpeg "$@"

# call image viewer, such as EyeOfGnome, to verify image is ok.

eog "$@"/bg.jpeg


Spero che questo ti aiuta in qualche modo!

- Sean
