Hey, I use k3b to burn my dvd-r's and my dvd burner is a 4xspeed burner.. What i don't understand is why k3b will only let me choose 2x or 1x (or auto but that stays at 2x). The dvd discs i have are 4x too..
Anyone know what to do ?

The latest version is 0.11.18. Which one are you using?

Well, now it doesn't seem to be the problem, now it just won't burn, it gives me an Input/Output error... perhaps the discs?

The exact error is:

:-(write failed: Input/output error
Fatal error during recording: Input/output error

my k3b version is 0.11.12

I used the command line to use cdrecord and this is the error i get

Ok, it's wierd, i bought dvd+r discs now and they still give me a similar error

:-( unable to WRITE@LBA=260h: Input/output error
:-( write failed: Input/output error
/dev/hdc: flushing cache

anyone please?

If you're trying to write to DVD+R discs have you installed dvd+rw-tools?

well
when i type locate dvd+rw iget this

mark@linux:~> locate dvd+rw
/usr/bin/dvd+rw-booktype
/usr/bin/dvd+rw-format
/usr/bin/dvd+rw-mediainfo
/usr/share/doc/packages/dvd+rw-tools
/usr/share/doc/packages/dvd+rw-tools/index.html

/var/lib/YaST2/you/mnt/i386/update/9.1/patches/dvd+rw-tools-51844

i've come to the conclusion it's not the discs but the computer itself.. I tried two brands(one was dvd-r, and the other was dvd+r).. i know for a fact that it burns in windows, but it won't in linux
