Is there a way to copy edited stuff back to the sdhc card so I can view on my HD TV via the camera?

This is a very good question that I wondered about myself. Also if the SD conversion in the camera is quite good, it might simplify that process. Hopefully someone has experience with this.

Bump. I can't google any answer.

Ray,
I really don't think that you can do this. As soon as you edit the clip, you break down the file structure that the camera needs to play it back - just like it does after you've shot a scene and want to review it.
There isn't just the video file to consider, there are other files associated with the clip such as the thumbnails etc. You've probably seen all the files anyway if you've opened up the AVCHD folder...

Thanks Robin. Guess I'll have to get a media player.
