Well, the point is that different inputs (i.e. DVD player, cable-box, PS3, etc.) will not have identical pictures, so need to be calibrated differently. Some TV's offer true independent settings for each input, but the Panny offers you three different picture settings (Vivid/Dynamic, Standard, and Cinema) which have factory pre-sets but can be tuned individually.
Now, your Plasma will remember which of the three picture settings you have assigned to a particular input. So, for example (this is what I do), you could tune your "Standard" setting for watching TV through the cable box over HDMI, tune your "Cinema" setting for watching DVD's through component, and tune your "Vivid" setting for playing video games over the other component input.
So, you've got "Standard" on HDMI, "Cinema" on Component 1, and "Vivid" on Component 2. If you buy, say, a new upscaling DVD player that has an HDMI connection, and you switch the DVD player to HDMI and the cable box to Component 1, the TV doesn't know that you've switched it! So, your DVD player will be on "Standard" and the cable box will be on "Cinema", which is the reverse of what you originally intended, because the TV memorizes settings BY INPUT.
So, again, check your Picture menu and make sure you are on "Standard" when watching via the cable box. You are probably actually still using the old setting your cable tech set up for you, since you switched the cable box over to component.
