HD-SDI by itself won't improve picture quality, assuming the HDMI chain isn't mucking with the signal (not necessarily a valid assumption, because of combo chips, systems-on-a-chip, etc. where you can't just get clean passthrough).
The real win from HD-SDI is that the raw feed out of the MPEG decoder is going to your scaler. If your scaler is better than the one in the player, then your picture quality can be better.
Plus HD-SDI runs over coax, and can run a looong distance with no problem, unlike HDMI.
Also, some people are lucky enough to have displays that accept HD-SDI inputs, in which case there isn't any HDMI/HDCP at all in the chain. Just like in the studios. Displays that accept HD-SDI inputs include some front projectors, and at least one plasma monitor intended for studios that I saw available to end users (the HD-SDI card was an option).
The sad thing is, HDMI was foisted on the hardware manufacturers by the studios. The companies making players didn't want the extra hassle, but they were forced into it.
I paid for every CD, DVD, and Blu-ray in our house. We have thousands of them. The studios should let me sign something that says I won't steal their content, and in return they should give me unencrypted content. But of course they think we're all thieves.
