Felix,
First of all, forget thx. It is virtually dead. Most DVD's have Dolby Digital encoding. Make sure you are using fiber optic cable or tru digital cable not just any coax. If you are set up right, the next thing you need to do is go to Radioshack. Yes, Radioshack. They have a decibel meter for around $80. You need to set the volume for each of the 5 channels from where you are going to sit when you watch movies. Do a test mode of your system. Make each buzz register 77-82 decibels. This would really tweak out your system. This way your system will be calibrated optimally. It will actually sound better than most cinemas. I assume you bought true hi-fi speakers not Bose. I sold Audio-Video equipment before I jumped on the MCSE bandwagon. Hope this helps.
