On a similar post, I've add this reply :
Last week, I've installed the drivers from 6.1 (22 December) and the last bootloader from Vu+ website (8 January) and it's better. Previously it was easy to reproduce "crashes" but now I can't. It's better but I still had a crash I can't reproduce. The box was recording and when I want to see a file (I chose the movie and I pressed OK), it crashed. I shutdowned the box but it crashed every time I try to open this movie. After I restart electrically the box, I could open the movie.
I have a question : on another post, somebody told me to launch : "shutdown -n -r now" but the box is unusable, it crashes nonstop. Now, I restart the receiver (with the menu) or restart electrically once the box have restarted from shutdown.
Is this command "shutdown" bad or is it the option "-n"? I've searched about this command and I've understood "-n" can do unpredictable results. Have you an idea?
