Hi, I have a Sony DVD burner DRU-710A and a AOPEN Combo drive 5232 AAH/PRO. I am having a very weird problem using Sony DVD burner. I can write DVDs (burn data - single and multiple session, burn iso image etc) using the Sony DVD burner but when I tried to read it in the AOPEN combo drive, I cannot read the DVD at all.... The DVDs can only be read when I used Sony DVD burner. I brought the DVDs to my laptop's combo drive and the same things happens. I'm writing with NERO 6 and mostly on the media DVD+R. Anyone have any idea what is wrong??? HELP!!!
