I have pretty much no experience with DVD-RAM disks or devices. My father gave me an old DVD-RAM disk that he was hoping I could get the videos off of it and either convert them to a standard DVD or a video file.
I checked my optical drive's specs and it did say it supported DVD-RAM disks. When I got the disk it was a mini-disk in some plastic caddy and was two-sided. I took it out of the caddy and tried to read it on my PC.
I was able to view the contents of the disk, but I was not sure how to playback the data, or even if I was playing it back properly.
The disk had three folders on both sides:
DCIM - which other than some subfolders was empty (I assume the camera had some photo feature that was not used)
DVD_RTAV - which contained three files: "VR_MANGR.BUP" "" and "VR_MANGR.IFO" "VR_MOVIE.VRO"
RTR_EXTN - which contained two files "RX.DAT" and "VR_STDUM.000"
I have no idea what any of these files are for, the only one I was able to make any sense of was the VRO file, which since all the others were a few KB in size while that one was in gigs as well as it's obvious filename, was clearly the video file. (I assume the others are some sort of chapter/metadata but I was not able to figure out how to read them after googling about it).
Trying to playback the VRO in MPC:HC or VLC worked..... but only kinda. It claimed the file was only about 3-4 min in length, which makes no sense for compressed video.... and eventually I found out why, the timer just plain doesn't work in any player I used. If I try to skip ahead/rewind it just keeps calculating nonsense times, and keeps going long after the video should have been over.
So I really have no idea what to do.
First of all.... did I even get all the files off the disk right? I just simply copied the files off the disk that Windows could see, but as I said, I am unfamiliar with DVD-RAM disks. Are they designed with any sort of multiple layers or metadata or something of that nature that I would have missed from just simply trying to copy the files as if it was a standard data CD or DVD? And if so, what method should I use to actually read all the data off of it?
And if I did get the data off the disk properly, how do I properly view it? Much less extract/encode it? I couldn't figure out how to try to load the BUP/IFO files to get proper chapter data, or how to even playback the VRO file properly since it's timestamps and playback length were utterly broken. And I have zero idea what the RTR_EXTN folder is even for or if that is some camera-specific metadata that is useless for trying to convert the video.
