PS3 or other bluray player into 1080i TV?

I have an ancient, 1080i, rear projection TV without either DVI or hdmi input. Does any bluray player or PS3 output 1080i by component video or do they all down sample to 480p with ancient displays like mine?
PS3 down samples as does my upconveting Sony recordable DVD player(480p), 1080i with HDMI cable.
I have the Panasonic bd30 blu-ray player, which will output blu-ray discs at 1080i over component (DVD-Video is output at 480p). Also, you cannot get any advanced audio (true dolby HD and DTS master) unless you use HDMI.
