    I keep getting 'error reading card' when I try to play back videos recorded on a gf3. Some times the error message comes up half way through the videos, other times it comes up right away. I was able to download these videos onto the computer (pc) and play them without any issues. I had no trouble viewing pictures on the camera. I m curious if anyone has seen this before?

    sounds like your card is too slow - i think Class 10 is what is recommended

    If the card is too slow, then shouldn't it fail to record? I would think card reading speed is usually faster than card writing speed, no?

    agreed that reading is faster than writing.... but in recording video the card is writing an already encoded data file from a buffer...

    in playing back video it has to read the file and then decode it before playing... maybe the buffer for playback is smaller or different from the recording buffer, and the card isn't fast enough to keep this buffer filled.

    Just a theory... check what the handbook recommends as an acceptable speed of card.

    Try reformating the card as opposed to just deleting files

    Does it do it with all cards or just one card

    How old is the card


    you get my point .... its more likely to be a problem with the card rather than the camera

    Is it a hacked GF3?

    Ok this is strange. I tested the same memory card again and it now plays video fine in camera. I did reformat the card but I am not sure if that was the reason. The card is a 32gb class 10, less than a month old.

    The Gf3 is running a third party firmware, but the bit rate did not seem to have gone up (still in the 18mb/s range).
