will a home theatre projector purchased prior to Blue Ray work with a blue ray player?

Solution
Yes
If they both have HDMI or component or composite video.
With HDMI the player will set itself to the resolution that the projector supports.
With component video if the output is higher that the projector can handle you won't get a picture. Connect the player via composite video to the projector, set the resolution to the native resolution of the projector. Reconnect the component video cables.
With composite video you are limited to 480p but you won't need to set anything to get a picture.

does the projector have HDMI? If than yes it 'should' work just fine.

Please note this does not mean the projector is actually projecting a full 1080p image just because the bluray player works with it.
