I turn on my Xbox, open the disc tray, insert the game, play and press the eject button. Something's wrong! It doesn't open! And the screen's black too! OK! I shut down the Xbox. Restart. Nothing! The screen's black and the disc won't come out! After millions of button pushings the tray opens! The Xbox OS is started too! I take the DVD out and close the empty tray, try opening it a few times: it works! I reinsert the game disc, the game starts, I play and push the eject button: it doesn't open! I've learned two things on this problem: it's not the reader and the tray opens with pure luck! Does anyone can help me? I mean it's an ordinary problem? Is there a trick to be used to open the tray and start the OS of the Xbox?
