Let me preface this by saying I know allot more about audio then video and that will be appearant by this post. Let me set the table a bit.

I have a Sony HS-51 projector with Directv fed via HDMI to my Integra pre-amp which is 1.3. I want to add a blu ray player and my question is simply what should do the processing, the projector? Do I have a choice. In other words my pre-amp has excellent (so I have been told) video processing. Now I have the pre-amp set to pass whatever comes to it untouched to the projector. If I were to have my pre-amp set to 1080i wouldn't the projector just reprocess this information anyway? I use the 1080i option for output from my Directv as I never got the crop issue fixed with my projector.

If I add a blu ray player to the mix should I continue to do what I have done in the past and just take the pre-amp out of the mix and pass the signal through untouched by my pre-amp to my projector?

Also, given I do not have a 1080p projector and I ask the blu-ray player to output everything in 1080i am I doing blu ray a huge injustice? By the way I have looked at high def on my projector in both 720p and 1080i and I can not tell the difference for what it is worth.


Thanks for helping this video idiot out, as always I appreciate the help.

Yep, just send it 1080i like your DTV connection, that way it won't need to re-sync to the different resolutions and let the HS-51 do the scaling.. Enjoy.

I had 51A. If your proc has 720p option set it up for that and feed the pj with 720p.
If Not 1080i either pass thru or direct from the D*TV box. Or try both and see which you like best. Most likely you Onkyo does a better job if it offers 720 down conversion.

Isn't the projector the end all? In other words, I can't take it out of the processing chain. No matter what signal is feed to the projector it is still going to reprocess it, correct?

It processes certain things (beyond the topic) but if fed 720p you will bypass the internal downconversion which was your original question.
