401s cant format dvd

i’ve been trying to burn to dvd media and it just won’t let me. about 2 weeks ago i could burn to the same media fine, did so 4 times. i used nero back then and i used the same media. when i goto burn any file to dvd in nero: iso, mp3 collection, data dvd, etc. when i try in nero it says:

start formatting disc before burning
formatting disc failed
lite-on dvd+rw ldw-401s session fixation error
lite-on dvd+rw ldw-401s could not perform disc at once
burn process failed at 2.4x (3,3,24 kb/s)

when i use nero to erase the cd manually it says its an illegal disc.
the media i’m using is khypermedia dvd+rw and it worked perfectly numerous times before. i’ve also tried to use memorex dvd+rw discs with the same results.

i’ve tried to use dvd decrypter and basically the same thing happens. it ask to format the dvd and i choose yes. then this happens

like i said i’ve had success with the khypermedia dvds, never tried the memorex till now cause the kh were doing fine. i have a spindle of dvd-r’s i could use but ther 401s won’t write to -r. is there a way to make it write to -r?

i’ve also done the eeprom utility upgrade for 401s and that didnt help at all that i could see.

thank you :bow:

Use DVDInfoPro to format the RW properly.
