I hooked up the Toshiba HD-A1 and I'm curious which one of these should I utilize? I'd have to use the 5.1 Analog to get the TrueHD via the HD-DVD player, which means I'll lose the back speakers in my 7.1 setup. Is it worth it? I can't test it out yet since I'm waiting on a couple of HD-DVDs to be delivered to me.
