It specifically addresses this issue. Hint: Using Firewire is a better bet.
Ok basically I have a Sony DCR-HC40 and have a movie recorded on the analog tape in the camera. How do I transfer that movie into my computer? I would like to use it for a project utilizing Windows Movie Maker, but am unsure of how to get movie into the computer.
When the camera is connected to the camera via USB, all the data on the memory stick syncs up, but none of the data on the tape does. Is there any way to record something from the tape to the memory stick within the camera? Is there any way to directly sync from the tape? Thanks!
