Not really. You will need to change the source on both the HTIB receiver and the PJ either way, so it doesn't really make a difference. Although after doing a bit more reading, it appears the signal may degrade slightly. You may not notice a difference, but if its all the same to you, best to run it direct to the display.

So, that's when I changed the DVD resolution to 1080i and then the pj read 1080i as well. Did I understand you correctly?
No, i don't think you did. Let me take a step back in the explanation- sorry if you know some of this already, but if you don't, you need to if you want to understand the input of the DVD player.
Okay, the PJ can *only* display 720p. Nothing else! Therefore, whenever you send the PJ a signal other than 720p, it will in some way convert it to 720p. 480i, which is all DVDs (except Blu-ray/HD-DVD) and TV signals (american at least, except the HD signals of course), will be de-interlaced (the i stands for interlaced, the p for progressive) and upconverted to 720p, because that is all the PJ can display. When the PJ says the signal is 480p, that is referring to the signal it is receiving, which it then converts to 720p.
If you send it a 720p signal, it will display it with no resizing/upscaling/deinterlacing. This is theoretically the best resolution to send it, if the source is that resolution natively! All other resolutions are processed. Most are processed by the PJ, but some are processed by, for example, the Oppo 970HD. You want the 970HD to process the image if the processor in the 970HD will do a better job than that of the PJ- and it probably will. If you set it to 720p, then the image will be upconverted to 720p by the DVD player, which the PJ will then display.
However, some people have said they get better results by converting to 1080i, the letting the PJ *down*convert (not upconvert as you seem to have misread from my post) to 720p. It is up to you which does a better job in your case. Try all the settings, and see which image you like the best. Remember that whatever setting you choose, the DVD disc only has 480i and the PJ will only display 720p- the question is how is the image processed from 480i to 720p. Different methods of processing will likely give noticeably different results- so it is up to you to decide for yourself which one gives the best.
The summary: try all the options, decide which looks best, set it, forget it, and don't care about all the technical mumbo-jumbo of how or why it looks the best
1. not sure- my PJ doesn't arrive until Saturday
2. Yes, the given life on bulbs does refer to the half life.
3. Yes, the unit must be in line with the screen- there is no horizontal lens offset. I would probably mount it in front of the screen, on the ceiling, likely between the viewing location and the screen. Mount it close to the max throw range, then you can zoom in if you desire. Use the mitsubishi calculator (linked a few posts ago by me and then again by someone else) to get a general idea on posistioning.
4. You say if you get a larger screen you'll cover up your... screen? Do you mean your speakers? In that case, I would reccommend an acoustically transparent screen. I've heard good things about the smx screens, but have never actually seen one. Google it if you're interested- though they may be a bit beyond your price range.
Monoprice has some electric screens in that range, although I've never seen one, so no promises as to the quality. Go over the the screen forum and you can find a thread on them.
5. never used it, sorry =/
6. Read my explanation to ravencr for more details, but basically: some have said that with standard def DVD players, they have a better image setting it a higher resolution and letting the PJ scale it down to its native resolution. Others say its best to leave it in the PJ's native resolution. Try it both ways and see what works for you.
