Le tridi 13 frimaire, an CCXXIII, Adrian Meyer a écrit :
 I am mounting an ISO through loopback and I get 5 messages from libdvdread 
 through lsdvd and 1 from perl crashing on the eval:
 libdvdread: Attempting to use device /dev/loop0 mounted on 
 /media/raid/Video/divx/iso for CSS authentication

 Bad name after device' at (eval 5) line 2.

Can you show the output of lsdvd -Op -x /dev/loop0? Please make sure you
distinguish stdout and stderr, for example by redirecting each in a separate
file ( log_stdout 2 log_stderr)?



 I am not a perl programmer. How would I manage to ignore STDERR in this
 section of dvd2concat to for lsdvd only if it was succesfull? The -q on
 lsdvd does not suppress the output:

There is no need to ignore stderr, it is already written separately. You
would not see it on the terminal otherwise.

What you report looks like a bug in lsdvd (its output in -Op mode should be
valid perl under any circumstance), but I would need to see the output you
get, because I can not reproduce the problem with my version and the ISO
file I have laying around.

Regards,
