There's nothing wrong with Imgburn it is one of the most recommended fre burners on this Forum. Where did you download your Window 7 Ultimate ISO from? Was it a torrent download as I see you have the pre activated copy?

I've burned many CDs & DVDs with ImgBurn and can't remember the last time a burned disc turned out bad. I let it burn at max speed with no issues. I would suspect the disks you are using first, then I would suspect your optical drive. It appears your drive doesn't support buffer underrun (Device Buffer on your screenshot) or you have it turned off. IMO, buffer underrun is essential to be able to burn disks with a high success rate.
