DSLR Help - Why are my photos messed up? (Canon EOS Rebel XS)

Hey guys, I'm trying to figure out what could be going on with my camera. For the most part, it takes amazing photos, provided I focus properly and such. For example, photos like this:
While sometimes, it ends up doing... this to them:
[Note: images resized for the forum]
and I have no idea what is causing this problem. And that's not the only glitch, sometimes those sections where the image is damaged will be just washed out, other times the color will be off entirely. I've tried formatting the card multiple times, but it doesn't seem to prevent the problem entirely.
So, to anyone who regularly handles DSLRs and knows more about digital photography: Please advise. If it helps, I'm using a 8GB PNY Optima Class 4 SDHC Card.

Right now I've given the current card a low-level format in the camera, so I'm gonna see how that turns out. First batch of photos seems clear, but I figure I need to give it more use before I can be certain. Thanks again, and I reeeeeally hope it's not the sensor
I KISS YOU!
Something has changed.
Yeah, does the image look bad when you take the shot and it is displayed on the camera's LCD or only when you review it later / download it to your PC does it look bad?
I KISS YOU!
more or less new and has done so since getting it. Maybe 1.5 months old at this point.
A glitch in the what now? And that was the same bird. It was taken on the canon's continuous shooting mode
So far, near as I can tell, only when I review it later.
1.5 months should still be under Cannon warranty. Just send it back. I have the same camera and like everyone else has said it should never be doing this. Stop wasting time trying to figure out how to fix it and just call them up and get it corrected. Usually their warranty department is pretty decent (I have dealt with them before on a camera with a bad flash). I have taken 1000s of shots and never once have I seen such a thing.
Then go get a nifty fifty lens and start having fun without having to worry about all this image corruption.
I KISS YOU!
There's a really fun movie called The Matrix. Don't watch the sequels.
As far as actual troubleshooting, there's no reason not to test other SD cards first since you already said you have some handy.
And yes, just stick with the first movie and don't watch the others..
Shutter problems do not produce perfectly straight lines along pixel rows.
I've seen similar problems with scientific CCDs where the ADC (the thing that measures the "counts" across the CCD chip) is a bit buggered or if there is a problem with the chip. It normally accumulates counts along rows, a bit like a CRT, which would give you that perfectly straight line. If it's lost its zero position as it moves down a row, it could create that effect. It could also be that the electronic shuttering for the chip (not the physical shutter) is out of sync, so the chip gets reset half-way during the read-out phase (depending on how the chip works.)
Most CCDs with a rolling shutter have the process Reset (clear the chip) --> Accumulate (collect photons) --> Read-out (measure the number of electron pairs generated in the chip) --> Reset --> etc.
Somehow I didn't pick up on the sarcasm
