I don't have this particular SDI-HDMI converter, but of course it does output 480i. Everything else would be out of the question. 480p is neither a SDI nor a HD-SDI standard. I have a bigger Blackmagic Converter box (everything to everything) and it handles SDI to HDMI just like the smaller boxes should. 480i in, 480i out.
An interesting question would of course be if it's handling video vs. PC levels correctly, but maybe fatjulio can answer this question.

OK, but here's the million dollar question: Does the BlackMagic or Gefen converter output 480-i- YcBcR out the HDMI jack? If the external converter outputs 480p, then there's no point in a good processor after it. The whole point of using the Lumagen, at least for me, is to get the de-interlacing they provide. If we let a cheap conversion box do that, then what good is the Lumagen scaler? You might as well just feed the 480p into the display.
I need to be assured the running SDI to HDMI means the converter outpits 480i withou any other alterations to the data. The Lumagen must also accept 480i HDMI.
480p is an HDMI standard
Are you sure your Blackmagic box is outputting 480i over HDMI?
