Philips, the one that was posted above with the pic, I think its on its way out though
, drive door doesn't always open and there are a few disks it will sometimes read fine, put it back in a few mins later and it totally blanks it, and ive tryed about 60 times with it!
I Do have a Sony DVDRW drive though incase it fails
I got Sony, Lite-on, Philips, and a few unbranded
