Since the solution for this is as simple as "just don't do it"
I guess I won't change it for 1.2.0. But I promise I'll do it
after that. In the meantime, just don't shoot yourself in the foot ;-)

Please try if increasing 

#define MAXNONUSEFULDATA (10*1024*1024)

to, say, 100MB or even more makes a difference, or just comment out
the lines

        if (exitOnFailure)
           cThread::EmergencyExit(true);

(both in remux.c). Maybe it just takes too long until it gets decrypted
data. You might also want to check your log file to see whether in these
cases you got an entry "ERROR: no useful data seen within nnn byte of video stream".

Let me know if this helps. If so, I might change it for 1.2.0.
