1. Start readong & posting your question at www.avsforum.com
That is more the spot for this type of stuff- use the Video PRocessors forum
I use a Quadscan V2.5 pro
It would be a SUBSTANTIAL SUBSTANTIAL upgrade over the internal processing of your projector.
Your 3 year old Mitsu does not have a Genesis chip thatdoes 3:2 pull down.
The Quadscan does.
I have a three week old Sanyo XP21n projector and the Quadscan kills it's internal processing.
If you have the $ it would be a worthwhile investment for Quadscan or HTPC, but buy from someplace with a return policy (AVS has $999 Desktop models)
Newer HT oriented projectors may be released later this year (but at $5k+) that will include superior internal scalers I suspect.

I got a DVDO Iscan Pro de-interlacer already, so not concerned about 3/2 pulldown anymore. Am wondering if old Genesis scaler chip in my Mitsu X100 is of relevent quality comparable to the current ones in scalers like the quadscan.

Posted on avsforum already, no reply, any other forum that knows about this stuff?

  In order of 3:2 (progressive de-interlacing) performance
  Poor- Mitsu internal
  Better - Quadscan (genesis)
  Best- DVDo Pro with Sil503
  Scaling performance
  None- DVDO does not scale, only de-interlaces
  BEtter- Mitsu internally takes 480p up to XGA
  Best- Quadscan
  
  In order of quality
  Poor- mitsubishi with no external device
  Better - Mitsu with DVDO de-interlacing to 480p
  Best- Quadscan scaling to XGA.
  You will note that your DVDO probably has better de-interlacing than the Quadscan alone, due to using a better chipset (s503 vs Genesis)
  However, the DVDO does not perform SCALING at all, while the Quadscan does (in your case you would scale to XGA).
  It is because of the scaling feature that I would recommend the Quadscan over the DVDO.
  Does this help?
