Is there a box that can downconvert 1080p to 1080i

I still have a CRT RPTV in my living room and am looking into adding a 1080p projector in the near future. In other rooms I have 1080p plasmas and LCDs. I just ordered an HDMI matrix splitter to feed all of my rooms from the devices on my A/V rack. My CRT RPTV is my only device not capable of accepting a 1080p signal. Rather than configure my devices to display to the lowest common denominator (and I'm not sure my lcds [computer monitors] will accept 1080i), I would prefer to just set my devices to output 1080p and stick a box in between my CRT and the splitter to downconvert the 1080p signal to 1080i so it will accept it. Is there anything out there that will do this?

What make model of CRT HDTV do you have? I am not aware of any that accept 1080p and if they do they interlace it to 1080i by separating the odd and even lines so they can be scaned on the screen in sequence. See the following link for an explanation.

It's a 2003 or 2004 55" Mitsubishi Gold something or other. I am nearly certain that it won't accept 1080p, considering it won't even accept 720p. What I'm looking for is a converter box that will take a 1080p input signal and output 1080i.

I believe you can set a video processor to input to the display to interlace 1080p to 1080i.

Personally, I would just set the output of your sources to 1080i. If your plasma and LCD's are any good, they will de-interlace the 1080i to 1080p without any problems.

Are you doing 1080p24 out or just standard 1080p30/60?

Mears,
Several manufacturers of top of the line CRTHD RPTVs sold top of the line "high scan" models which could scan at either 480i or at 1080i. These models would only accept 48i, 480p or 1080i as inputs
