Nervous-I was planning on buying the 42" Sceptre LCD as soon as it became available at Cosco, but I am now becoming nervous because of the poor SD resolution issues I am reading about. I am planning on upgrading my RCN cable to HDTV, but a lot of content still comes through in SD. Can anyone that owns a 37" Sceptre comment on this issue? If I purchase the 42" Sceptre, will SD viewing be worse than on a lower pixel rated flat screen? How about DVD with a progressive scan DVD player? Any feedback will be appreciated.
