I've got DVI, component and S-VHS connections to my front projector (Sharp XV-Z10000). I have the DVI connection straight from my LG LST-3410A tuner/HDDVR, as that is currently the only DVI source I have. As the projector is fixed pixel (720p DLP), it upconverts all other inputs to that format. The projector's upconvesion is so good, that running the LG's output through component or S-VHS shows only a very slight image degradation, noticable mainly in closeups of people's faces. This is pretty impressive, when you realize that there is a D/A & an A/D conversion interposed in the signal path. So, my feeling is, yes, it would have been nice if you had thought to put in a DVI cable, but you haven't lost a hell of a lot if your projector does as good a job of upconversion as the Sharp.
