I have an Onkyo ED-901 Dolby Digital decoder and it's worked great with my Onkyo 828 receiver playing AC-3 encoded laserdiscs for the past year and a half. I picked up a Toshiba 2109 DVD player a few months ago and have noticed that when playing some DVDs, the sound will "flutter" and the lights on the ED-901 will flicker. If I turn the unit off then back on, the sound will play fine. Other DVD's don't exhibit this problem. Anyone know what's going on here?
