JVC DVD Recorder Disc 'Read' problems


Recommended Posts



I borrowed a disc recorded from TV from a friend using a JVC DVD recorder. I'm sorry, I don't know the model.


I tried read the image to create an ISO on the HDD and get a warning message that the following space requirements are required and exist:


Required: 8,795,690,336,256 bytes (8,388,233MB)

Remaining: 481,438,957,568 bytes (459,135MB)


Firstly, the DVD disc is single layer, so 4.7GB in size. It reads and plays fine in a DVD player software package.


The harddrive is actually 2x320GB drives in a RAID array (448GB free space).


The option to continue anyway doesn't work, as it says not enough free space.


Here are the details from the disc:

To show that Windows is reading the disc correctly, here is the DOS directory listing:



Volume in drive E is JVC DVD_ROM

Volume Serial Number is 76C0-0608

The recording in question is a movie, so approximately 2.5 hours long, not the 954393:30:72 reported.


The IMP_ID is given as JVC DVD_ROM UDF, and the drive doesn't auto finalise. Without being finalised it is unreadable under Windows. Hence it has been manually finalised and works as described above, and doesn't work being Read by ImgBurn.


As the disc isn't copy protected and is to watch a legally recorded show I can dump it to the HDD as folders/files, but I had intended to do it as an ISO and watch using VLC. Makes it nice and easy to watch then delete.

I can't do anything with that.


The drive is reporting some enormous size for the disc.

I can only go by what it's telling me.
