What makes this happen?I use dvd decryptor,dvd shrink and nero.Sometimes I get perfect backups and sometimes 'they take a while to warm up'.(Wont play unless they feel like it) Another question....are there better quality burners out there??Do they affect burning reliability??(I have a liteon + -)If so how?? Do better quality discs make more reliable backups??If so what brands?? Thanks in advance. Reg PS this is a great site.Without it I would have never found the two excellent programs above.
