Sony DCR DVD108 not finalizing disc, lost data

I noticed that too with my "VR" (and NOT "Video") formatted disks. I don't think you can finalize the VR ones. Instead you have to use the Sony Import tool to grab the videos. If you are like me you probably remember using the import tool with Video formatted disks BEFORE finalizing them and it takes forever to copy them. They must be finalized to view on other devices, copy using the import tool quicker, etc., but VR formatted disks seem optimized for importing (and can be edited on the camcorder directly.

put youy dvd into DVD RECORDER. it's much easier and longer time then finalize it on it. good luck
