I have two SD cards I used for Panasonic Lumix TZ7 camera, which usese AVCHD Lite.
I ran out of space and bought a bigger SD card and now want to combine the videos from the 2 old SD cards so that I can have it for convenient viewing with my camera.
What happens is that if I have index.bdm file from one SD card, the videos from the other SD card are not viewable; i.e. the camera can't locate it, and vice versa. I suspect that index.bdm file records information about where the video files are, and thus having one index.file doesn't allow it to realize that there are more videos from the other SD card.
I do not know how to edit index.bdm (althought I tried with notepad without success).
Thank you in advance for your expertise!
