Transferring PC videos TO a Sony Cybershot?

It probably won't work but here is something to try:

Make a short video clip with the camera. Then look at the memory stick with the computer to find out the name of the video and what folder it is in.

If the camera makes .avi videos, you will have to convert your home videos to the .avi format.

Then rename the video to a name similar to the one the camera made.

i.e. If the camera named its video Vid00023.avi, then you should rename you home video to something like Vid00034.avi.

Then put your video in the exact same folder where the camera put its video.

That will give it a chance to be recognized by the camera. But I doubt it will play in the camera.
