I don't know if this will help, but this is what I've had to do. First, I downloaded MPEG Streamclip and purchased the MPEG-2 PLAYBACK from Apple and installed it.
Next, I connected the Sony Handycam DCR-DVD610 to the computer via the USB cable that came with the camcorder. Only the DVD showed up, not the camcorder itself.
I opened the ONE file listed on the DVD and then COPIED the .VRO file to the desktop. After it was copied to the desktop, I then opened it using Streamclip and then used that program to save it as the .MPEG-4 file.
This has been a royal pain in the tush--the material I read online indicated that the camera was compatible, so I THOUGHT the camera would be an easy connect and transfer.... I was wrong. The software that came with the camera was incompatible with my Mac. I've wasted MANY hours fighting with the process and trying to figure out how to save/export the file. I could not simply open the .VRO file from the DVD itself--it only played the first clip on the DVD and not the entire collection of video clips I had filmed. It was only AFTER I copied the file to the desktop and opened it from there that I had any luck.
If this helps someone--great. If someone knows of a shorter, less time-consuming and frustrating approach, please let me know.
I do like the camera, but I feel that Sony's information about the particular Handycam I purchased was misleading.
