It also appears that Harmony does NOT have the codes for the 905 yet..... it had me input about 6 IR commands and then it determined that the 905 was similar to the 505..... of course with none of the correct inputs.
I ran the 905 for about 4 hours after getting it set up... checking all of the devices I hooked up.
HTPC Gateway 901X
Sony CX995V (400disc Mega Changer) does not output 480i via HDMI so I had to use Component.
Everything played nice so far....... all sources audio/video worked without a hitch.
The only popping I heard was when I had the volume up pretty far (0 db) and was going in and out of the setup to tweak the subwoofer.
I had exactly ZERO HDMI Sync issues.
My display is an InFocus 7210 projector (720p) that uses a proprietary version of DVI they call M1. As the 7210 is a revision of an older projector the DVI design is also older... this created a problem with my Pioneer Elite 84TXsi in that the Pioneer was ignoring the secondary display frequncies of the projector and locked all sources to 720p. This is due to the EDID data block of older DVI connectors is only 128k rather than the newer HDMI spec of 256k.
The 905 does not have this issue and now I output:
1080i from my HD-DVD player
"Native" from my HD-DVR (which means 480i, 720p, or 1080i depending on station)
480i from the Mega Changer
720p from the Xbox 360
1280 x 720 from the HTPC
The first three are then run through the Reon and sent to the projector at it's native 720p.
I don't have enough experience to decide the best way to set the "Picture Options" but I did turn mosquito noise on to low and then mid.
I did spend some time with Phantom of the Opera in HD as I have probably watched this movie more than any other I have... and after switching the audio back and forth I liked the sound of either the PURE mode or the THX Ultra2.
I will try and post the addendum that concerns the picture menu... it is actually quite short... only one half of a page. Onkyo was not overly verbose with their descriptions.
