I just received my 921 HD Receiver and the HD (High Def) channels have outstanding quality (particularly the HDNET and Discovery HD channels). On my Samsung 43" DLP TV (HLM437W), viewing SD (Standard Def) channels has been very bad. The picture quality is grainy and distorted. I have tried Component, S-Video and Standard connections, but have not found much difference in quality. I have tried all combinations of the display settings and 720P and 4x3 #2 seems like it works best. Does anyone have any suggestions? Is there any chance that the next software update will help this problem?
