Pstwo will no longer read certain games

[Robochicken]

I just had a customer return a pstwo w/ MI that he had dropped. It was fully functional except it would no longer read certain games. He says it seemed it was an issue with games above a certain size. I opened it up and noticed his DVD pot was at 834. I increased it to 908 and that fixed the problem. It was a 4D pstwo. Just wanted to share in case someone has the same issue.

I'm using the duo2se modchip, before when I would put in a burnt ps2 game, it would work perfectly fine. But now (months later) the disc seems to be freezing in game and skipping a lot. The ps2 reads the game, but its just that in game it skips a lot. The game "lags" a lot. Anyone know what could be causing this? It sounds like a ps2 problem, not the modchip, but I'm not sure. Could your method be the problem Robochicken?

your problem is probably the media or dvd burner write speed, could be laser to

With the v12 adjustment I did I guess it depends on the laser you have. I wasn't sure how to tell the difference so I just looked at my v12 type which was a 4D and found another 4D pstwo that was working fine, measured the pots and used those values you see in my first post. I think it's better to go by laser type in case the values are different.

If you have the old PS2 here's a link for adjusting it's pot:

So if you want it to read more types of media you'll have to raise the pot value? I just purchased a brand new V12 Laser and it's barely reading a lot of different brand backups. With Ridata discs it gives me the disc not readable message.
