You didn't tell.
Composite is handily beat by HDMI but can be equal if the video source is say below 480p.
I have a 50" plasma & a 42" plasma. I receive a better picture on the 42" using RCA plug-ins than I do on the 50" using HDMI cable,both HDTV's are panasonic and are on AT&T. Is this possible.
The TV's are 50"1080p and the 42" is 1080i
