My system (virtually ) consist of DVD player, TV, reciever(probably) and set of speakers. 1)I do understand why I need "A" in the reciever - to decode 5.1 sound coming from my DVD, but do I need that "V" stuff, if I can connect component output from DVD to TV directly? 2)If I don't need any "V" could I do the better sound using separates, asuming that I want to spend the same money(around $500) 3)Does the DVD's 5.1 ready ouput has the same sound quality with that one coming out from the reciever? 2)Does any dvd player can read dvd-a format or it's something extra I need to look for? Do I need any special requirements from the reciever in this case, or digital connection will be enough to transfer the data? What about SACD?
