i have a 411s liteon running the fsoj firmware. my problem is that if i write discs at 4x, a lot of em end up with artifacts from about half way thru and stuttering sound and picture. it is a toshiba sd220e. the lastest media i am using is pio-data 4x dvd-r g04. using k-probe on a couple of the discs ive had probs with, the errors average around 30 with a max of 50, and hardley any errors on the other scale. (ie a very well burnt disc) so what could be causing this.
you end up with coloured blocks and symbols popping up on the picture which gradually gets worse, then the sounds starts to break up. when i write em at 2x, they are fine even though the k-probe scan is noticeably worse than 4x???
