My backup dvd's dont work in my new Toshiba hd-a20, my originals work. I backed my dvd's a while back because of the kids, but backups wont work, only the originals. Some are on Sony dvd+rDL & memorex dvd-r. I updated firmware to v1.6, latest version. I used CloneDVD & AnyDVD to back up my DVD's, they work on my sony upconverting dvd player without any problems. I actually download some music videos & burned them to DVD using NeoDVD & that works perfectly.
