Καλησπέρα αντιμετωπίζω εδώ και καιρό ένα πρόβλημα χαμηλής ταχύτητας εγγραφής μόνο σε DVD παρόλο που στα παραθύρια δουλεύει κανονικά στο K3b πεισμώνει και μου χαμηλώνει την ταχύτητα στα Χ6 ενώ σηκώνει Χ16 MAX.

Υπόψιν δοκίμασα και το brasero τα ίδια.

Ακολούθησα τις οδηγίες που λέει, σας παραθέτω τα αποτελέσματα απο τις εντολές.
