A while back I saw a post here on this subject but I can't find it now. It contained a handy advise how to conveniently transfer the files en mass from the microSD card to the PC via the Internet connection. It gets boring to do it individually with so many small files.
BTW, is there a way to make those video file fragments bigger than 2 MB?

I don't know how to transfer files en mass, but I recently posted instructions for transferring files without removing the card: just right click the file and select "Save target as . . ."
Regarding file size, this is the same on the SD card as on FTP or network storage: files of higher resolution and longer duration will be larger, up to the file size limit, which I believe is 3MB on the stock firmware and 5MB on the beta firmware.

Yes, I know about that single file save method but it gets really boring with a few dozen small files. I thought somebody mentioned a method to save a group of selected files as well but maybe it was a dream. :-;

Well, this is the weird thing: in my case they are not the same size. The event-triggered video clips are of the max 3 MB size, but the on-demand recorded video on SD is made up of 2 MB segments. Perhaps your SD clips were event triggered, so that's why they are the same size with the FTP clips. What I am trying to do is to record a low frame rate video and store it on SD and later play it back in a fast-forward way till I see some activity. Kinda' like what you would do with a VCR to skip commercials. I just don't understand why the segments are even smaller than the event triggered clips. But right now my other problem is finding a software out there that would concatenate all those small video segments into a single file in batch mode for playback that does not reprocess the video. I found one such lossless AVI file joiner but it does not do batch processing; just appends one file at a time.

I didn't see any posts about copying from the SD card other than the one I mentioned. You might be able to do it using the URL commands discussed in the thread on that topic, but I haven't tried that.
You are correct: I have written to the SD card only using event-based recording. You might be able to do what you want using third party software (or D-ViewCam); I haven't tried it.
If you were recording to a network drive and not your SD card, it is possible to view a series of snapshots and make it look like a video. Just open the first jpg in Picasa or other picture viewer, give it time for all the thumbnails to load, highlight the first thumbnail and scroll to the right. Depending on how fast you scroll, you can almost make it look like a movie. Not sure how I would do this on the SD card, however.

Snapshot recording though would not record the sound or the time stamp. Video recording, even at small frame rate does record both. That extra info can be useful.
