Tip & How-To about Microsoft Windows XP Professional
So the deal is you have a DVD-Video that you created and you want to make a backup copy OR your DVD Player skips on playback due to a surface defect or deep scratch, you have already tried to clean and repair it and still it wont work, check out my tip on how best to do this HERE
The quickest method is to create an ISO image using one of the top applications like ImageBurn or CloneDVD or DVDShrink the thing is al three fail on CRC or read errors on either the IFO BUP or VOB files so what can you do?
Using ImageBurn my personal favourite and selecting the VSO Patin Couffin Driver with a low read speed of x2.4 from the I/O settings interface and the default settings it will cope similar to Alcohol 52% FE and create the ISO upto the point where the first bad sector is then try to finish the ISO, it also tells you how many sectors are being scanned and the number of bytes in real time;
Using DVD Shrink pulls an immediate Cyclic Redundancy Error on the D: drive where the DVD-Video is inserted
CloneDVD pulls on IFO read error on VTS_04_0.IFO as this is a major requirement for successful DVD navigation it contains important navigational information, such as where a video chapter begins, and where audio and subtitle streams exist within the movie (VOB) file.
IFO files are not encrypted but without it this software can't correctly re-author a new DVD video using this method, the BUP file in VTS_03_0 is not a problem as it is just a backup of the IFO and this file is fine in this case, so only this one error is thrown up.
Alcohol 52% FE will attempt to create it native MDS image file format and as lon as you check skip read errors and or use data precision management then it might work the main benefit is it will log each sector error and create a graph to show where the errors are in relation to the total number of sectors.
AnyDVD will rip any DVD, go figure, whether it be CSS or NOT if there is an IFO issue it will throw this error, not much help to us with a damaged DVD there then
SO WHAT CAN YOU DO THEN READ ON !!!
IsoBuster v2.7.0.0 is to the rescue, in the Professional mode you can extract the VIDEO_TS folder from the File menu it will scan the DVD for errors and then give you a list of the files that have Unreadable Sectors, you don't need the AUDIO_TS folder unless you will be using older standalone DVD players to view the result, its also in v2.8 Beta HERE on Filehippo it costs $29.95 (£20) an well worth the money.
If you select insert Dummy and Apply always on the first sector that has problems then it will do this in this case at 42% for all subsequent bad sectors through the 100% complete 21 file extraction.
NOTE: This may take upto 4 hours depending upon the number of bad sectors within the files until finally it finishes with a full list of recovered files in this case original scan found 2 files a BUP and an IFO from different VOBs
The final result shows 2 extra VOB read errors withing the two VideoTitleSets (VTS) linked to the IFO and BUP files, into which IsoBuster has added dummy sectors to make complete files that will now play.
If you wish to then check the extracted files within the VIDEO_TS folder then use DVD Shrink it will scan all files very fast and you will see that the read errors are now GONE !!
SPECIAL NOTE:
In this scan and extraction there is a complete BUP (IFO BackUP) file for VTS_04_0.IFO as the BUP is an exact copy of the IFO and is good then just copy this good BUP and rename it as the IFO in place of the recovered IFO this will improve you playback for that Video Title Set.
The opposite can be one for VTS_03_0.IFO that had an unreadable BUP file just create a new BUP from the good IFO, this will help if the IFO ever becomes unreadable on the new DVD that you want to create.
You can apply this method to CSS encrypted DVD content using Slysoft's AnyDVD, but only if you own a licensed copy of the original to recover information from a badly scratched DVD-Video
