I have successfully been watching dvd's created with DVD Shrink, ripit4me, and or dvd decrypter. Note, I am now using dvd decrypter HD and dvd shrink. Everything is buring just fine, and I can play them on my PC of origin, but when I play them on my home theater dvd (yamaha) player it says no disc. I am using the same discs as always, Taiyo 8x DVD-R. Help!!!
