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?
