I've had a Toshiba SD5112 DVD-RW for about two months and have had no trouble simply watching movies with it. In the past week I've been trying to copy some DVDs with various programs, but my drive could not recognize blank memorex DVD-Rs. Now when I try to play a normal DVD the video works normally, but I get no sound. If I open the Audio_TS folder it shows up as empty. I've tried updating drivers and removing all the DVD copying software I had installed, but nothing has worked. Any help would be GREATLY appreciated.
