Have chipped about 20 version 5's over the last 3 months with messiah 2 and all of them have shown signs of reduced cd-r reading capability.
PS1 backups on cd-r work fine but these only read in at 2X speed.
PS2 backups read at 24X speed and problems seen range from -taking a bit longer to load than ps2 original cds- to -not reading ps2 cdr's at all-.
This is not suprising as version 5 consoles r gettin on a bit.
All consoles modded read and played traxdata 4X ritek dye dvd-r no problems (burned at 4X) so not all bad news.
