my guess is new chipped ps2 (which works fine if i understand correctly)is likely to be v5
your old 1 is v3 or v4 i gueess
dvdx works with old ps2(its correct version regionx for a v4)
new ps2 (it wont work u need newer version regionx for a v5)
hope u understand
basically regionx has different version old ones work on v4 but not v5
buy new version regionx then it should work on v5
or new ar2 v2 has regionx built in it works on v5 with messiah clone fitted (double press reset as if its ps1 game or dvd film)
