info above is most likely correct
but
i had v4 with neo 2 for a year and a half (heavily used) had cap fitted saves the laser
often it would strugle to play dvds,all it needed was a cleaning disk run through it
the ps2 is still playing fine with messiah 1 in it now must 4 year old now


cleaning disk are a few £ only its worth a try
especially if your neo has the cap fitted

no cap most likely the laser is dying

dvd films struggle because they are constantly reading
most ps2 games load ,play after it has loadedtry gta vice city this loads as it plays i think u see the effect
