I don't have the cleaner, whatever that is, but I am having the exact same problem on my new Dell system. I found your post because I am searching all over the internet for SDDMI2 and I came across this site. Please let me know if you find out what this is.
After running the cleaner the first time on my Dell Dimension desktop and rebooting the computer it entered the "New Hardware Found" dialog saying that the device "SDDMI2" was found.
I have no idea what this device might be and I had no luck with the autoinstall or trying the device drivers CD that came with the computer - I keep getting "software not found" errors.
I tried doing a restore of the Registry and that made no difference.
I had done quick tests of most of the computer features and don't see anything, yet, that doesn't work.
