OK, I got a wild idea...
I have a sony AVCHD camera and I can download the video images. when I do, I get a bunch of m2ts and modd files. I have been able to congert them to AVI and use them...
Is there a way to put them back in the camera and play them from the camera again?
When I connect the camera back via USB, it shows up as a hard drive and has a file/folder structure. But when I look around for the folder to put them in, I can't find files with the same extension. (of course it wouldn't be as easy as that.)
Is this even possible? Perhaps the files get converted on the way out and are not readable by the camera any more. I don't know.
