I've got a Sony DW-U18A which seems to work fine for cd burning but screws up every time i burn a movie (i get pixellation, skipping or it just does nothing!)
I've tried dvdsanta, nero and dvdshrink (tried burning from 1x to 8x) A few discs works fine upto about 70minutes then start to mess up, i've tried different dvd players and tried playing them on my pc which seems to work slighty better but not much.
I've turned off all other apps while burning too.
Any suggestions as to fixes or am i stuck with a duff dvdrw? misaligned laser? Are there any diagnostic programs i can use to help?
