I recently purchased my XBox and have a problem with the left and right channels. Here's the setup: H/K 520 Receiver DefTech BP 2000 Tower main channels DefTech 2002 CLR Center channel DefTech Surrounds XBox connected via Monster Cable 400x and 100x (component and toslink cables). During several cutscenes and sometimes during gameplay, the right channel volume is so low that I can hardly hear it. If I turn the right channel up to +10 and the left down to -5, it is almost corrected, but during other scenes it goes back to "normal" and is completely out of whack. I also have a PS2 (toslink), GameCube (stereo), and DVD (toslink) hooked up and have never experienced this problem with them. Any suggestions?
