Someone please help. I've switched different brands of media.. from protek to verbatim now ritek based on everyones oppinion but I'm still getting freezing during playback.. after a successfull burn.. If I reinsert the dvd back into the computer it says "no disc" in shrink.. then I get freezing when I try to play on my home player.. I've tried shrink+decryptor and shrink+nero.. I've tried the original firmware and updated firmware.. no help.. could someone plz tell me what I am doing wrong.
