Edit subtitle without re-encoding whole DVD



I converted some Divx files to DVD format , using Convertxtodvd software. It took some time , but the final result was good , but I forgot to add and edit some subtitles and I would like to do that without re-encoding again .

I made an Image of the DVD to my hard disk . Theres a lots of vob , ifos and other stuffs wich I dont know what for .

Is there any kind of software ?

Thanks for any kind of help .


You will have to encode to get the subtitles into the video.
