Hi there
No answer to your specific question, but I has helping a friend setup a PC to his KV-34XBR910, which I think has the same super-fine-pitch tube. We didn't have time to try the DVI connection, but connected the PC to the TV using 1080i over component video. We did compare OTA digital TV, in HD resolution from the PC versus the same HDTV channel converted to analog using a CECB attached by s-video. Of course the analog SD image was less detailed than the HD, but it was still watchable and acceptable. The HD was better, but if $500 wasn't available for the PC then he could certainly live with the analog SD. (CECB was a ChannelMaster that has an anamorphic mode to utilize the full NTSC bandwidth for widescreen content.)
Given that the PQ difference between the same source in SD versus HD was not that huge, the differences between DVI and component for the DVD player might not be that significant.
BTW I looked at the service manual, and has baffled by the processing block diagrams. It is not obvious how the component video is processed versus the DVI; i.e. there was not just one video selector switch. Is component video digitized and processed like the DVI, then converted to analog to drive the CRT? It did not look like the DVI was immediately converted to analog, and then processed like component video.
