So, why don't the manufacturers list what the native capabilities are? None of them list 720p etc.... I think that is what is throwing me.

Good point on the test tones, I already have a sound meter, where would I buy a cd/dvd like that from?

The main problem with the sub is that I don't know what it should sound like. Sound silly? I am finding it great with movies, but I watch a lot of music dvd's and I am finding the results a little disapointing, the bass is very slow, it's a Kef psw2500 and matches the rest of my system, reviews said it was good for music? Guess I'll have to get back on my knees.....

Cheers
