If VLC plays it, even choppily, the reader is probably fine. If it fails using your camera, the problem is probably not the card reader. Please try to copy it to an internal drive. For what it's worth, you only need to copy the Amazon link up to the ASIN code: https://www.amazon.com/Sony-CFexpress-Type-Reader-MRWG3/dp/B0FJ2XXQ5C
