How do I copy DVD’s and keep the subtitles?

I want to copy my DVD MOVIE collection to be able to an external disk drive.Two inquiries:

What format(s) will continue the subtitles intact I have a experiencing problem, so the subtitle is essential.

What software regarded as a use

Many thanks!

1.Try WinX DVD Copy Seasoned (download coming from
http://winxdvd.com/dvd-copy-pro/download.htm)
A COUPLE OF.Choose the “Copy to be able to single MPEG-2 file” option.
SEVERAL.The output is due to MPEG2 structure while keeping 1:ONE PARTICULAR ratio as well as preserving many Menus, Subtitles & ‘languages’ bonus.

You implement DVDFab DVD Ripper.It could rip MOVIE to the majority of popular video tutorial formats such as MPEG-4, DivX, Xvid, H.264, AVI, FLV, WMV, for example.
Hope it really is helpful back!

Use WinAVI DISC Ripper and also set alternative “blend subtitles in video”.
