New V12 Lazer And Possible Boot Disc ????

[psxmodsuk]

Hi all first of all ive read a thread here that the new v12 dosent read dvd-r very well , on the box it says it reads dvdrw - and + has anybody tried RW.
Also with the console having a flip lid why couldn't we use the swap magic discs as boot discs we would just need a spring or something like the old ps1s surely this would work and then if the console screws up its still under warrenty .
Please post your findings regarding any of the above
