Dvd-r Boot Problem

[filippos]

Hi please help me if you know about this.
My ps2 is pal - 3004R with a NEO 2.2 installed and i use AR2 V2.
My cd-rs play fine but i deal a problem with the dvd-r 's
I start AR2 pressing reset button down , I eject ar2 and insert Dead or Alive 2 Platinum while i have chosen dave mirra max and when i insert the original dvd DOA2 the cd is beeing read(i can hear it) but a clicking noise appears as if it cannot read the table of contents. if i leave the reset button the tray opens but a mechanic noise is heard twice like it still trys to read the cd. then i insert the dvd-r backup press start and nothing happens. Note that i have managed to work it properly some times(without any noises) but most of the times this happens and the cd doesnt load.
Ps . I changed the capacitor just in case that was it , but still the same prob.

thanx for your time
I believe only Charlie or Arakon could help me about this but if anyone else could i would appreciate it.
