A more extreme variant of #3.

Apparently, drive permissions aren't the problem. You want to show the
movie too (as well as read it from the drive), so look at your X server.
On my system, /etc/X11/XF86Config has

Section "DRI"
    Mode 0666

At one time I had

Section "Module"
    Load "dri"

but that's commented out now. ISTR a module "glx" being somehow involved...

Anyhow, check your X config file.
