Problem of detection of .mov on camera ( EOS550D) plug on USB


today, I plug my EOD550D on USB for playing videos on the WDTV,

the WDTV reconize the camera and, it’s possible to show pictures, but it"s not possible to read videos

wdtv say what there is no folder.

How are the files named by the camera?

Try to copy one to your PC, and then copy it to a USB memory stick and see if that will play.
