TSSTcorp writer error..

Sounds like your DVD burner is defective. Sounds like time for replacement. Good luck!

First i had a writing problem... it was taking ~~70 minutes... I deleted the driver for secondary id channel (MasterDeviceTimingModeAllowed) and restart comp... it fixed.. wrote a dvd ~~15min.. but didn't read that again..

Understood. Still sounds like a flaky DVD burner. Does it read other media properly?

Yes,, it's reading dvds that i wrote before and the other dvds written by another writers..
