Creating images from video DVDs

[Hazza]

I'm a long-time user of ImgBurn and very happy that there are generous souls who share their excellent efforts with the rest of us - thank you !

 

I have just created an ISO image file of a video DVD. The DVD was created by my domestic DVD recorder (Panasonic).

Doing some checks, I discovered that ImgBurn modified the two IFO files and their associated backup BUP files.

I also imaged the disc using another well-respected product, which produced an image identical to the original disc.

 

 

The modified image produced by ImgBurn plays correctly on my PC (VLC media player) and my streamer.

The identical image produced by the other program does not play on either PC or streamer.

Windows Media Player plays both images correctly once they have been mounted on a virtual drive.

 

Obviously I'm very pleased that ImgBurn has taken steps to make the image usable. 

I'm curious to know what it did since it is obviously important to know if there are any wrinkles in the transfer process.

I think I saw a fleeting screen message "corrected ...", but unfortunately the log file doesn't shed much light in this instance :

What you've done there is rebuilt the file system based on the files that were on your source disc (i.e. you used Build mode). That's not the same as making a sector by sector copy of the disc (i.e. using Read mode).

 

It will have corrected a few values in the IFO / BUP files so they were correct based on the new layout of files within the image (sector offsets etc).

Thank you for your explanation.

 

I had to use build mode because the recorder somehow created several extra empty tracks on the disc, which ImgBurn (rightly) didn't like.

 

All is now clear ...
