I have to add some of my own experience to the above post.

Even if you have the sixth channel enabled and present, it won't work properly with HP COS and probably any other disc with that flag problem. The 1050, no matter how it is set-up, can't decode these DVDs properly. It's a different issue than not having the sixth channel speaker present and on.

Let me say this a different way. I have a sixth channel speaker enabled on my 1050 with a speaker attached to the output. Upon playing HP COS, the 1050 kicks to 6.1 mode and I lose the majority of the information in my surrounds. This is, at least the way I'm hearing it, different than just losing the center surround information.

Now that I've said all that, I also believe that their will probably never be a fix from Outlaw for this problem. It's a decoding issue that isn't going to go away without some internal changes and I'm not expecting anything, even from Outlaw, for a receiver I bought for $500.

Thank you 73Bruin for you investigation into this issue.
