As the OPPO has two HDMI-in's it would be nice to be able to connect an ATV this way too.
Bizarrely, I find the Avant is very good at upscaling ATV content. No idea why. ATV content looks superb on the Avant. No need to push that through the Oppo.
One other thing that's annoying me about my Avant is the constant light<>dark panel changes it makes whilst you're watching the TV. Who thought this was a wise idea? "Guys, we need the Avant to check and refresh every 30 seconds!". It's noticeable and, worse, sometimes goes dark to light, to dark, back to light, without any changes to the room lighting! The BV11 was better at handling low-light conditions than the Avant.
