this may not be the right place for this question, but it is about DVD players...
I've been looking at buying a DVD player. I've noticed some have Optical and Coaxial audio connections. Some even have a bunch of RCA-type connectors for 5.1 audio out...
I am getting confused. If it says it has DTS or Dolby digital audio output, whay are there so many different types of connections??
