FWIW, I have a DV-50 and have run it through an iScan HD+ video processor via its component outputs [interlaced]. I found this to be the best picture I ever got in my system [Sharp XV-Z10000U projector using the DVI input from the iScan].
I did try the DV-50S and was very disappointed with the video [and disappointed with the standard DV-50's video too] which is how I ended up with the iScan. Since all of that, I have had my DV-50 modded by The Upgrade Company and an SDI output installed. The SDI was NOT worth the money, but the Upgrade Company's work definitely was worth the money.
