Demos not working on Real C64

The following demos don't work on my real c64 :

Royal Arte/Booze Designs
Nine/Reflex
Irrational/Chorus
Death and Glory/Covenant

Always when I load them my c64 hangs up in the first or second part of the demo. Already have tried to load them with another c64 and also with another power supply. I have even copied the demos to other discs in the case that the discs are damaged. On Emu those demos work fine though.

Anyone can help me? I wanted to enjoy those demos on the real c64.

Oneder also turns off the AR hardware in the beginning of the demo because the demo would crash later on. The reason was an AND (zp,X) which i used to waste 6 cycles in 2 bytes. Sometimes the high byte of the adress would be $DE, and accessing (also reading) $DE00-$DEFF with active AR = crash.
