I've posted a thread a few days ago about my PStwo laser reading only CDs, and good people halped me with that. A new laser was installed in my system. The PStwo worked flawlessly for a week, and now it's getting on my nerves (again). A few backups play almost perfectly. Others simply don't start, or give a RSOD. I've noted that Verbatim (MCC02RG20) discs are slow to load, and videos flicker or hung for a second. But Imation (FUJIFILM03) discs directly are not seen by the laser. My question is: WHAT NOW? Should I turn the pot slightly to make the laser read DVDs better, at least the Verbatims? Could this be a modchip problem? SHould I make another fix? Should I throw this Slim PStwo against the wall?
