Firmware Upgrade or NOT!!!

[ancient]

Hi guyz and gals

I'm one of those guyz that likes to backup his own bought copies.
Dvd films etc

I notice that my dvd writer Pioneer A06 has new firmware available

I've had a few coasters - Dont play on my gear but they play on friends about 20%

My firmware is 1.05 and 1.07 is offered

Is it advisable to upgrade or stay with 1.05

As i sense each upgrade tries to make it more dificult to back up

any you guyz or gals please advise/comment

regards
