Finally I figured out how to do it. These are the steps:
- Create a subdirectory called
VIDEO_TS
and move all files there. - Create an DVD ISO file by executing:
genisoimage -iso-level 1 -dvd-video -volset-size 1 -o output.iso root_folder
- Mount the DVD ISO by executing:
sudo mount -t iso9660 -o loop output.iso /media/cd/
The result will be a compatible ISO image which can be played using any video player (Totem, MPlayer, Dragon, etc.).
For those ones who are too ubuntufied, you can use K3B to create a DVD project and select "Create image only" before burn it.
Anyway, thanks for the answers. This site is too different from what I was used to in StackOverflow though, I have to say. It seems that some of you just read the title of the questions before answering. Maybe my English is too bad :)
