Does not sound like a supported feature.

That is, moving content to the PC is pretty supported. Alter the card's contents and all models will not play this any longer. That is, this is proper and for now, no maker appears to detail how to put video on a card and have it play on the camcorder.

Nothing really busted here. Just not a feature you find on today's common camcorder.

Once the video is on the PC, the date/time is usually embedded in the video data. Some players show it, some don't.
