From the manual, you can set the output
levels by pressing TEST and adjusting the
levels with VOLUME. How do you set
the output levels if you want to use AVIA
to set the output levels?

If you are using AVIA (or Video Essentials, which is very similar), there are test tones included that serve the same purpose as the 1050's built-in test tones. You would simply use those test tones to do your calibration instead of the 1050's tones. Using AVIA or VE may be easier, because (at least with VE, which is what I have) they stay on one test tone for longer, allowing you to adjust that speaker more carefully before moving on to the next speaker's tone. This is most true if you are using an SPL meter.

One potential problem with using AVIA or Video Essentials is the center surround speaker (if you have one). Because neither discs were created for 6.1/7.1 material, if you have SURR 6.1 on while using AVIA, you may find that the test tone sent to the right surround will be split between the right surround and the center surround by the 6.1 decoding. This will throw off your calibration (you will set the right surround too quiet). It is best to use AVIA with the 1050 in 5.1 mode, and then use the 1050's test tones afterward to set the center surround.

Exactly how would you do that? From
the manual I don't see a button for
output level adjustment. I assume
pressing the TEST button makes the
VOLUME button the output level adjuster.
But if you are using AVIA, what button
do you use to adjust the levels.
Pressing the VOLUME just adjusts the volume
and not the output level, right? Sorry
if I'm misunderstanding.

Play with the "SELECT" button on the remote some (along with the four "arrow" buttons, I think -- I'm working from memory and a copy of the manual only as I'm at work right now). You'll find that you can set levels for the center and different surround speakers there (totally unrelated from the volume of the 1050). The idea is to get 75dB on one of the main speakers using the volume control, and then set the channel output levels up or down for the center and surround speakers so they also give 75dB.
