I want to switch from windows to linux, but before the switch I would like to try them out in the Live CD.
I downloaded the iso and created a multiboot usb stick ( by YUMI Multiboot USB Creator ).
I can boot into Ubuntu Desktop 12.04 64 bit LTS and Linux Mint 13 Mate 64 bit. I can access the hard drive from there and I tried some video with the default player comes with them ( e.g: GNOME Player and VLC Player ). The player opened but the video didn't play. However, I can play the same video in Puppy Linux. ( Puppy Linux doesn't has a choice over 32-bit or 64-bit )
Maybe my CPU didn't support 64 bit? Here is a snap from CPUZ:
CPU: AMD Phenom II X3 710
UPDATE:
Yesterday I tried to boot into Linux Mint and give it a second try. The video played without problem. Today I boot it again and it didn't work. No Video is able to play. Only the video player appeared with a black screen. No warning, no error message.
I wonder if it is about the video card? I am using ATI Radeon HD 4830 video card. I've heard linux doesn't have good support for hardware. But how can I be sure of this? I can't install driver within the live cd linux ( or can I? ) before I really install them on my hard drive.
