Hi there,

I have use DVDFab most of the time to backup / convert my BDs but now and then I also rip DVDs with it.

For nearly all DVDs I ripped DVDFab worked without hickup. Now friends have asked me to make them a backup of a DVD produced for them during a cruise they did last year. This is understandable since the DVD itself does not look THAT high quality and has some high emotional value for them.

The copy protection I run into seems to be similar to ARccOS Protection (corrupt parts on the DVD which are omitted during playback) but also included corrupt navigation information inside VOBs as well as a corrupt filesystem on the DVD (there seem to be 100GB of VOB files on the DVD :)).

DVDFab failed to open the original DVD claiming the media is corrupt. Almost all other commercial product (beside the one with the fox) also bomb out.

I was able to rip the content of the DVD to HD with dvdbackup (a Linux tool) but one ends up with 100GB of VOB file with identical content on HDD :)

dd_rescue came to the help and could simply rip the DVD to an ISO of reasonable size which I could burn. The resulting copy worked like a charm.

When I try to open the ISO generated by dd_rescue with DVDFab it still claims the media is corrupt.

Extracting the ISO with a tool of your choice (e.g. 7Zip) result in the mentioned 100GB of VOB files.

This is really a funny copy protection. I was close to "rip" the content to separate files with MPlayer and re-master them to a new DVD without protection.

Let me know if you need more infos to evaluate this issue. The ISO generated by dd_rescue has no corrupt sectors in it anymore since dd_rescue fills them up with zeros. So my educated guess is that DVDFab (and other tools as well) run into issues when either parsing corrupt VOB infos, the corrupt file system or both ?

I can not crosscheck with the product that has a fox as icon since I had it installed for evaluation a year back then. So re-installation is not possible.
Sources in the www indicate that the "Rip DVD to HDD" seem to work with the DVD mentioned above. :D

TIA,
