Some data recovery programs will extract MPEG files from damaged DVDs, but CnW goes one stage further and will recreate a complete video disk image, with no extra tools required.

This is a tool takes MPEG files, resequences them, and generate the relevant .IFO and BUP files.

Most data recovery programs will allow recovery of the basic MPEG and then require external software to convert these files into a format that will play on a standard DVD player. Sometimes Windows Media Player will display the recovered files, but at time it will only display the first few seconds.

The tool will allow for one or more mpeg files to be joined together, and relevant control files added.  These files may then be copied to a DVD and run on a standard video player

The first stage of reconstructing the video structure is to use the function Create Video Disk from MPEGs which is found under the menu Tools. The program will create a new subdirecty VIDEO_TS and merge all the mpeg files into a series of VTS_01.1.VOB files, upto 1GB in size. There are then two control files, VIDEO_TS.IFO and VTS_01_1.IFO 

The merge operation is very simple.  Select the directory with the required MPEG files.  The files must be in the correct order so it may be necessary to rename some files to ensure they are in numeric sequence.  By default, CnW Recovery will create files with a 4 byte numeric extension, which will be sorted as required.

The first stage is to select the files to be merged.  The select all button is the most common way to do this.  When Merge Files is selected, all files are merged into a sequence of chapters.  If more than 99 files, files are merged in groups to keep the total number down to 99. The files are then stored in a new directory, VIDEO_TS. 

Creating DVD disk

Having created the DVD image it can be tested by double clicking onVIDEO_TS.IFO and typically Windows Media Player will display the file. To create a phyiscal disk, the files must be copied to a DVD using one of many DVD writing or burning packages.  Some software pacakages (such as Roxio) detect that the files are a video disk and will not let files be writtens as a data DVD.  For these pacaks, it is necssary to use a DVD duplication routine.  Examine the DVD writing software manual for more details
