It would appear there are already several versions on MR firmware being used as suggested by "thewall". I know of 2. Using the procedure you can find the following 1. Power the unit off. 2. While pressing together the "Play" and "Open/Close" buttons, press "Power". 3. In the display you will see the Play and Pause symbols. 4. Now, using the remote control, press the "Menu" button. With each press of the button, you will scroll thru the different versions of the the unit. First is the "DRV", followed by the "B/E" and finally the "Panel". Using the front panel button, power the unit off to return to normal operation. Mine is DRV 030307 B/E 6237 Panel 0043-f (this matches the version No on the file) thewall has 0042-f While the French on http://www.homecinema-fr.com are talking about 0041-f So this might explain some of the difference we have been seeing. Anyone else care to check??
