I bought a 100 pack of these from Newegg when I got my DVD burner, DVD-R 8x, and I have only made one coaster, which was my fault. They work fine in every DVD player my friends have used, as well as in my burner and dvd-rom on my PC after buring with AnyDVD and CloneDVD, the problem arises when I put them in my roommate's new DVD player. He just bought a Zenith DVB318 that has the upconversion from 480i to 1024i. All my burned movies with these disks play but skip a lot or sometimes don't go to the menu, when you select play move, it would just go back to the loading screen. I have re-burned movies to my Fuji DVD-RW's and they play fine. Has anyone else had this problem with the Zenith? I am wondering if its just the media and if so what you would suggest. Some movies play without a problem with the disks, but some skip or don't load. Its just so weird because they work on the JVC and RCA players we have playing around and on my friends Yamaha.
