I have had my 1050 since December and have generaly been thrilled with it's performance but there have been a couple of unsolved troubles. Upon initial startup I noticed that in speaker test tone mode, the sub does not emit low frequency tones. Then I noticed in stereo mode as well as ALL pro-logic and DSP modes that the sub does not work at all! Even after major tinkering. Anyone else with this trouble? Also, when playing DTS DVD/CD's, after stopping the disc and changing to a different sound format, the 1050 freezes in DTS mode, and will not change until I change the source. Any thoughts?
