I have two sd870is 2G in each and use them for stereo pics and vids. I am currently running (ixus860_sd870-100c-0.9.8-735-full). I recently and for the first time messed with video parameters and jacked up the bitrate to 3X. The camera stopped recording on it's own after a short time. The video clearly had much higher detail. But then later after bringing the bitrate down, the next recording resulted in what I would guess is a full card. One cam stopped on it's own and I couldn't access the card "card error". I can not access the videos on that cam. The other cam did not do this and I was able to view those videos.
Did I just use up the memory on that cam's card. Is there a way to keep that from happening in the future? Thanks, Pantelis
