The attribute indicating the image is rotated is stored in exif metadata. Canon has many unique metadata tags and it's possible that the TV does not read them all correctly, but your PC software does. [This tool|http://www.sno.phy.queensu.ca/~phil/exiftool/index.html] allows you to dump all the metadata. I suggest that you compare a rotated file that works with one that does not.
This is a known issue, and Apple has a fix posted here
HOWEVER, that fix is Mac/iPhoto specific. It is useless for me. I have the same issues, however I use Picasa on WinXP for my photo management. I agree with the previous poster, Apple probably just needs to improve the AppleTV's EXIF parsing because there are a lot of variations out there based on app.
The weird thing is that some photos are displayed correctly, and some are not. I haven't researched enough into whether it's based on Camera model, or which application rotated it (Picasa, Photoshop, WinXP Browser, etc..)
Some photo cataloging software saves the rotation in the catalog and does not change the exif data of the photo. You may have rotated the photo in Picasa and it views correctly there but it will not be rotated in other photo software.
Modern digital cameras sense the orientation of the camaera and seta value in the exif data to indicate upright or horizontal. This can be fooled if the camera is held at an angle.
I use ACDSee and it has the capability to change this EXIF setting. Note that this is different to rotating and saving a photo. The first method only chages a flag, the second method re-writes the image and there is some quality loss. Do a Google search on loss free jpeg rotation. There is a list of loss frre capable software.
