In the settings, disabled [ ] Burn Results To DVD
Also make make sure [ ] Delete Output after successfull burn
This way, the output will stay on your Hard Drive, and will not auto burn.
I always do this, then burn with CopyToDVD v4.0
As for subtitles, I use PowerDVD to play .VOB files on my PC.
Check in the menus, if there's a way to turn on the subs in Media Player.
They are not turned on automaticly, you need to activate the display of subs, just like on a DVD !
