i just bought a toshiba sd-r5112, and i've managed to rip a movie from dvd decrypter just fine (i can play the vob in power dvd just fine), however when i burn it to dvdr, the process seems to go fine except when playing the dvd through out the whole movie the audio is ruined with this medium-high pitched glitchy noise, sounds similar to a raygun sound effect. i've tried burning with both pinnacle instant copy and nero, at both 4x and 1x and it doesn't seem to make a difference. i've burned divx files to the dvdr in data format and they sound just fine. any suggestions? thanks.
