Hello Khalid, I'd skip using the stop function and go straight to the mode button once the player is done loading. I did this with several hybrid cd/sacd's just now. I was able to switch layers each time I pushed mode. I did this several times on three different hybrids: sacd>>>cd, cd>>>sacd, sacd>>>cd. I will admit; however, that the unit is a bit quirky with hybrids. A few of my hybrids get "stuck" in the loading mode and take as long as 1 minute to load. But this is only with a few hybrids that I have and not the norm. How many hybrid discs do you have? I take it that all your hybrids stay in cd mode, no matter what. I'd suggest turning the player off at the power switch on the back of the unit, wait about 10 minutes and power the unit up again, (although you may have already tried this). Turning the player off and on may reset the player. Good luck. Stan
