thanks for your reply. Yes, you are right
they both pass the code you suggested. However, there is one more place where
this error message is coded (line 160), this is where the following error

but as far as I have checked, an answer to my question does not exist. I have
installed everything fine (including gr-video-sdl part) on Fedora 4 (and the fm
examples work fine) .

This is strange.
Is this the error you
FYI: gr-video-sdl is not installed
realtime SDL video output window
will not be available
And you don't get this error when you run
(I put the code of test_video-sdl.py at the end of this
Both usrp_tv_rcv.py and test_video-sdl.py use exactly the same code
to check for the availability of video_sdl.
This is done in these
from gnuradio import video_sdl
print "FYI: gr-video-sdl is not installed"
print "realtime SDL video
output window will not be available"
So or both should output nothing, or
both should work.
Can you check if video_sdl.py is actually installed and
where it is installed.
Mine is located
can use the following to find all instances of video_sdl.py
or if locate isn't installed/configured
