Looking at DG720

[tim1970]

I am looking to upgrade my sound system. Currently I have a PS3 hooked to an older 5.1 system with no HDMI input. Money is definitely a factor now, so I can't go with a more expensive system right now. My questions are as follows....


1. What else do I have to buy to go with this? I am fairly certain I am going to have to buy a powered sub. (I don't have one now). Can I keep my other speakers though? Maybe just add 2 more to take advantage of 7.1?

2. Does this system do anything with the video, or is it just a pass-through? The reason I ask this is because my HDTV is only 1080i, and will not support any 720P signal. Also, my HDTV is DVI, so I would be using a HDMI - DVI cable from the receiver to the TV. I heard a rumor that this will not work with this system. Is this correct?


3. Looking at an image of the back panel of a 720, I see 2 outputs for FRONT A, and 2 outputs for FRONT B. What is this for?


Any other suggestions for receivers in the same price range will be gladly appreciated. (Especially if this one will not work with my HDTV)


Thanks
