I had the same problem with my Hitachi 59. Tried pot tweak. Didn't work. I use Verbatims from Singapore and I burned them at 2.4x with ImgBurn btw. Still no go. Played originals as well. I think Hitachis just blow. It has nothing to do with the laser cause I put it in a Sammy and it worked fine. For whatever reason, it just won't run backups. Could have something to do with one of the MS system updates. But nobody's really looked into it cause nobody likes Hitachis. Do yourself a favor and swap in a BenQ. Or a Lite-on if you have a spare (more expensive on eBay, but it's the best possible drive).
I've flashed three Hitachi drives so far. All of them have read and played backups just fine. All they needed (As most drives do) were a pot tweak.
