Please Help: vob.passthrough back to DVD

I i uses vob.passthrough profile is it possible to transfer them back and burn to a DVD later.

You should be able to burn them to a DVD as a data disc using Nero, but not with DVDFab because the files no longer have a DVD Video compliant structure and cannot be used as a Source in DVDFab. You could restore them to DVD structure and burn them with ConvertXtoDVD from VSO.

Thanks
Do you know if ConvertXtoDVD converts to DVD without reencoding or not?

Yes it does,and if I was re-encoding I'd use a real encoder..
Try FAVC which uses HCenc or CCE to encode for better quality..
If you want to author a new DVD w/o re-encoding,then you'll have to demux and remux back with an authoring tool..pretty easy actually...
You could also create a VIDEO_TS folder, rename your single VOB to VTS_01_1.VOB and save it in your new VIDEO_TS folder
Now you need to create ifo's and bup's...DL IfoEdit open your vob and create IFO's make sure to save to the same folder....If successful just burn your new VIDEO_TS folder which will now have vob's ifo's and bup's...Use IMgburn to burn it..I know it seems like a pain in the but and it is much easier with a one clicker,but it works,try it......
You could always just re-rip your original...

Thanks
