This is lame

Hey all
I have a Liteon LWD 811S DVDR drive, upgraded the firmware to the latest version, now the drive doesn’t recornize DVD+R medias anymore, and it doesn’t play DVD+R backup movies.
What do i do now?
I tried to reflash it in Safemode, but its still the same.

Thanks for the help

Uninstall the drive from device manager and restart. If that doesn’t help, then use better quality DVD+R media.
