Wow, I've had some dts tracks that I've ripped with dBpoweramp and use replay gain with none of the problems you are describing. I wonder if it's a problem of the decoder or the ripper you used. I worried about the jumping to save the stereo but after a few I gave up on that. I hope you solved it because that could be very bad on the old speakers. -- Nonreality -IF THE RULE YOU FOLLOWED BROUGHT YOU TO THIS, OF WHAT USE IS THE RULE.- HTTP://www.last.fm/user/nonreality ------------------------------------------------------------------------ Nonreality's Profile: http://forums.slimdevices.com/member.php?userid=15723 View this thread: http://forums.slimdevices.com/showthread.php?t=82265 _______________________________________________ ripping mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/ripping
