knight1024, sorry, I misunderstood your question :o
I thought that you have problems with burned discs, not with pressed ones.
Pressed discs can actually give these problems if there is a manufacturing defect on the disc. This happen sometimes, and the only solution is to ask for a replacement from the store where you bought the disc.
A common cause of defects in pressed discs is that the disc is warped, but in some cases the defect is not noticeable with eyes.
Moreover, some standalone are rather picky, so even a little defect make the disc unreadable. In this case, a solution is to create a copy of the disc. Often, computer drives are better readers than standalone players.
Sorry again for misunderstanding your question :flower:
