Default Questions about exposure & light metering...

I'm trying to learn how to better shoot in manual mode. One way I'm trying to do this is to get exposure readings in program mode (say 1/60 at f2.8) and then shoot that same shot in manual. However, when I take the pic in program mode it turns out fine. When I go to manual and plug in these same settings (same shot as program, same lighting, etc.), it is terribly underdeveloped. What is going on? No flash is involved, so that's not a factor. What is program accounting for that manual is not? I'm really confused about this. Any help? Could light metering have anything to do with it? Also, we BRIEFLY went over light metering in class the other day and I'm still very confused. My canon A80 has 3 choices: evaluative, center, & spot. I'm not sure what these mean (even though I went back and read the manual) or do. Thanks so much for any help you could give me or resources you could point me to.

Who is freezing cold...is it spring, yet?

Seems unlikely that you can get wildly different results *IF* the settings are the same for your auto and manual shots. So you should check to make sure the settings are the same by looking at the EXIF data. In particular, take a look at the ISO. When set on auto, some cameras will boost the ISO in what it considers to be low light.
