@ chompito,
Have you ensured that your DVD Burner has the newest most current up to date Firmware available installed?
Have you noted #2 posting 3rd paragraph comments? “Fotis†doesn’t actually manufacture any Media and any “Fotis†branded Media will be re-badge Media from some other manufacture which will not be top of the line quality error free Media and the use of this Media can cause less than desirable results. Your “Really Strange†“Failure Message†“Finalize Failure†problems are all typical classic problems when poor quality problematic Media is used.
As previously stated if you desire quality error free results Verbatim DL MKM001/MKM003 Mitsubishi Kagaku Media is the only DL Media that consistently provides quality error free results. All other DL Media (including “Fotis†branded Media) is considered suspect and should be avoided (not used).
