            Doesn't lock display and runs nicely in background now...
            Comment about bladeenc locking the display is only valid for very old versions of BladeEnc. BladeEnc now runs nicely in the background as well if you use the -quiet switch or change the progress indicator (-progress=[1-8]) and redirect output to a file in order to supress terminal output.

            Running bladeenc in background
            I don't know if it happens only with me but I haven't seen anyone complaining about problems with SIGTTIN/SIGTTOU running bladeenc. Anyway, I don't like to leave a display locked for days while encoding a large batch of files in a slow machine so I wrote a very simple wrapper to allow me to run it in background. It is available at (
