Pioneer 105 and datawrite 4x..... help!

[ZIZZI]

Hello, I have a problem, I have bought dvd-r datawrite 4x (red) on supports princo.... and if them burn to 2x all ok, they are perfect..... to 4x instead to the end of the movie there are freeze of image and mega-pixel-greens.
my firmware is the 1.21 official. what I can do? it's a bug of my firmware? if I put the "Pioneer A05/105 v1.30 - RPC-1 + 2x4all AND 12xRIP Final"?

it don't matter what f/w you use
datawrite reds have dropped in quality
until they are now pretty much useless.
Datawrite yellow 4x
Bulkcrap orange 4x
still seem to work.........
princo are just unreliable and have huge 'batch quality' problems
