I guess my thoughts / concern would be if I'm watching some stuff on TiVo (all the same input on the receiver):

I watch a show like, say, "24" .. and it's intense and in HD with a good soundtrack, so I want all compression off.

Then I put on a M*A*S*H, where there's NOT a lot going on in the soundtrack, and I want the commercials quiter, so I want some compression.

Then I watch Soundstage and I want it off.

Then Joyce goes to bed, so I want it on....

Might be a bit of an extreme example, but if I have to go five steps into a menu each time.....!
