ok - update was successful. Took about 20 minutes, and was very painless. Only hitch is that you need a Windows PC that has a serial port, and serial ports are getting to be a bit rare on new PCs nowadays.

Post-update, my versions are as follows:
* Main 1.04
* HDMI 1.00
* Net 1.00
* XM 1.00
* Sirius 1.00

So that said, it only updated the Main (I was 1.01 before). **** I'd be interested to hear how these FW Version numbers match against the units anyone's receiving from Outlaw.

Sorry Jeff, I dont have a list of what was fixed in the update - nor do I have a before/after comparison of the sound since I just hooked up the 886 yesterday.

I needed to fast-track the update to 1.04 since I have an Audyssey Pro tech coming over tomorrow to install the "Pro" license key and get me calibrated.
