I'v had my dru-720a for about 4 month and worked pretty well until about 2 weeks ago - now when burning a movie, single or DL, it either fails immediately or starts crawling at some point at 1% every hour or so (newer firmware didn't help). No, I didn't call Sony support - after doing some google research on Sony products in general and other user experiences with the 710 and 720 in particular, I saved my time and frustration and bought an Iomega. I am not happy about the number of (expensive) DL media coasters it's created. I'll never buy another Sony product.
