Hi everyone! I have a different problem with each of my burners. I am using a Compaq Presario AMD Sempron 3400+ with WinXP SP2. My OEM burner is a HP DVD Writer 740b, it's about a year old but rarely used to burn. The problem I am having with it is that no matter what program I use to back up my DVD's, it will only burn between .3x and .6x. Never any faster. I have uninstalled it and the drivers but still no change. It reads just fine. It worked fine for the first week I bought the PC and then it just suddenly changed. The other burner is a Sony DVD RW DW-Q28A. It burns up to 16x. However, it seems that 95 percent of the DVDs I have burned lately start screwing up after an hour and a half into them, give or take. The screen will slowly start getting "blocks" in the picture and then after several minutes, it will either lock up altogether or just get progressively worse. Any ideas on this one? It is almost 2 years old I believe. Any help would be greatly appreciated. Thanks!
