I really wish that they would make a THX ultra certified universal DVD player. Is a THX ultra certified DVD player necessary to get THX sound right? I will have a THX processor and amps. my speakers are High end def techs. I was planning on getting the DVD-2200. But wasn't sure if thx dvd was dire or not. Are the DVD players so good today, that THX cert. is not necessary to get good sound out of your THX process/amplifiers? George Lucas's speakers are not THX certified?
