How to merge/combine and/or convert VOB, BUP, and IFO into one file?

[gordes04]

I ripped a DVD to my hard drive and what I have now is a Video_Ts folder. In the folder it has VOB, BUP and IFO files. I know that you can just simply burn these files onto a DVD, but I was wondering if you can combine/convert all these files into one single video file(AVI, MP4 etc) so when you open the file you still have the menu and special features in tact? And if you can, how would you do the same procedure if you have a Video_TS folder and an Audio_TS folder when I also have from another DVD that I ripped?

You can't convert to MP4,etc and keep the menus and special features intact but you can make an image file(ie ISO).

Oh, missed the menu/feature requirement. Tmpgenc has Divx authoring software (with menus):

You can use ImgBurn to make a big DVD ISO.
