PS1/2 Some games are working and some not. Why?

[Slavio]

Hello.
I'm totally new here and I found that forum by looking for a solution to my problem with a game for my ol'good PS2.
I'm using SwapMagic 3.8 for quite a time now. Every game works fine, until now. Yesterday I wanted to play Persona 4, but every disc I burn doesn't work. I boot SM disc, swap and launch P4 disc, TV is going dark like before every game... and that's it. Disc is spinning endlessly and nothing more happens.
I used Verbatim DVD-R like with every game. I burned with speed 4x and 2x but effect is still the same.
Of course I patched ISO before burning with ESRpatcher.

Anyone have an idea what can I do to make P4 working?

I would be gratefull for any help.

Maybe try 8x, to low is not good aslo.
Back in the day I got every game to work only with Chaos Legion I got lag in the music.
I tryed every dvd+r/dvd-r and speed, in the end I play this nice game off HDD.
