I used After Dawn 2 years ago to learn how to burn DVD's. Now I need someones help again. I have a NEC 1100a DVD burner and all of a sudden, it stopped working. It will read audio cd's and text cd's (Word, Excel items etc.) but it will not read any DVD I have in there. Everyone says I need a decoder. Great! Where do I get one? I have tried everything. Uninstalling and letting "Found New ardware" to try and fix it--no good. I did a Firmware update and the flash worked and it says the drive is working properly. Any ideas anyone? Decoder, where can I get one and is a decoder the same as a driver? Thank you very much in advance!
