ok, I don't know anything about Tvs but I've had my Sammy hlp5053 for about 3 months now. Intially, I purchased the HD receiver for D* (i currently have D* with a Sd Hughes receiver with only an S cable, no HDMI or VMI). After reading about the Mpeg4 conversion, I decided to return the HD receiver and wait until the new hardware comes out. Now in the meantime, I'm stuck watching SD through D*connected through my S cable. I've read about all the tweaks to do in the SM but I'm afraid, very afraid, that I'll screw it all to hell if I go in there. The TV looks ok to me(only a little better than my old bigscreen rear pro TV). But I feel like I've spent all this money on a nice TV and not getting it's full potential out of it. I don't think there is any ISF techs down here to calibrate my TV(houston, TX). Any advice that is not scary to do to get more out of my TV until I get the new HD receiver. Any simple advice? Thank you.
