Firmware prob ? sony dw-d22a

I have had this writer for about a year now and all the sudden takes 24 to 48 hrs to burn a movie when it used to take 1-2 hrs. Norton scan shows no virus’ and I don’t remember downloading any new programs that would interfere with it. Tried to update to vrersion bfs2 with no change in burning time. Any suggestions ? Thanks !

No burner would need 1-2 hrs to burn a movie, and of course no 24-48 hrs…

Enable DMA for all drives, then make a burst speed test using Nero CD DVD Speed.
