Everything seems to go well, and I get the .iso where it should be. The size of the .iso file created is just over 2 GiB.
If I burn it to a DVD using Brasero, I get a response which says “Success” at the end. If I burn it with K3b, I get between 95-98% burn, and then an error message “Fatal Error”. But neither the Brasero nor the K3b burns can be used.
The k3b issue has been already reported in the past, despite the error message apparently the disc was burned correctly, however consider using only brasero, until you solve this issue at least.
Once burned, at lowest possible speed, verify the disc md5sum
, insert you media into the optical drive and in terminal write:md5sum /home/jjb/Downloads/PCL2010.isomd5sum /dev/sr0
(use /dev/sr1 if you load the disc in a second CD/DVD unit)
if the two results matches, your disc is correctly burned.
The fact the burned image doesn't work, most likely is due to some other cause. May be you are running an old kernel ?
If yes, most likely you want to use the mylivecd option --gzip or --lzma
(from terminal verify with: uname -r
Or, may be your system doesn't have enough RAM ?
