I have an extenal Dvd burner Pioneer dvr110d, I am attempting to burn back ups of some DVD's with popcorn but I am receiving the following error: Sense key = medium error Sense code = 0x11, 0x05 L-EC UNCORRECTABLE ERROR I ran the DVD thru MacThe Ripper before hand as well I have a G4 with plenty of space etc. I dont have iDVD but I also have toast which gives the same error. The driver seems Ok as it recognises and burns Cd's just not DVD. Any ideas anyone?
