Today I got the little problem where I was not able to run the DVD to my this laptop.
I searched and found the tips to run it in my 9.10 karmic KoalaUbuntu.
First, I have read that why this is happening… and I got this link
It says why some of the formats are not suitable sometime.
Second, then I installed Ubuntu-restricted-extra package to my system. Somewhre it says that these packages are by default installed but I installed again.
Third, still there is no sign of my work, so then you need to run this shell file…
apt-get install ubuntu-restricted-extras cd /usr/share/doc/libdvdread4/ sudo ./install-css.sh
Thats it, now the DVD is running in my laptop.
