I am using dvd combo. I have a strange problem. While I experience no problem in opening data dvds and read/install programmes, I am unable to open DVDs from our ThinkDigit alone. (The cds from "Digit" easily open with Auto run absolutely no problem) Either I get an error message "It is not a valid win32 file" when I directly doble click on the red "Digit" folder (Opened via Windows explorer) 0r if on right clicking on the individual folders I get the file could not be opened as either the write memory or the read memory is partially read. My service engineer says there is absolutely no problem with my Windows XP service pack 2 ESYS system. Can any member help me?
