I have an older Mits HD TV without HDMI and my receiver is a Yamaha RX-V1 that also lacks HDMI. How much of the A2 can I actually use? Will I get HD-DVDs in 1080i? What about SD with the newest flash? Also, what do I do with the audio? I currently use a Yamaha DVD player that supports SACD and DVD-Audio so it is using the 5.1 input on my receiver. Will the A2 provide either DD or DTS to my receiver through the digital output when playing HD-DVDs?
