I tried changing
vcd:///dev/sr0 to vcd:///dev/scd0
/dev/scd0? Is this a typo? It should be /dev/sdb, assuming sda is your HDD.
there are 4 sata slots on the motherboard. File system shows sda1,2,3,4. i tried using /dev/sda2 /dev/sda3 /dev/sda4 but they don't work -it was presumed sda1 represents the hard drive
is your vcd media good?
that i can't say but k3b was able to extract some of the tracks and convert them into mpeg files. some mpeg files ripped by k3b were of zero size and i presume those tracks may be unreadable etc (ie the vcd could be bad -hence the error)
