I was not only referring to the XRGB-3 on it's own, but the XRGB-3, EDGE and Optoma.... and whether the mini (assuming the bugs are sorted) could comfortably replace these THREE items, to provide the same performance of each individual sum (240p processing of XRGB-3, 480i deinterlacing of EDGE and scaling of Optoma).
Edge vs. Mini: I don't see any point in which
the Edge would be better.
Optoma vs. Mini: 480p processing is better on
the Optoma, but
the Mini is close. Lately I talked
to sombody who bought an Optoma and didn't
like the 480p processing at all. He prefered
the Gefen for upscaling. I guess
the Mini's closer
to the Gefen than
to the Optoma.
XRGB-3 vs. Mini: different 480i handling
If you can live without
the Edge for it's 1080i MOVIE and HD-TV processing capabilities, throw it out. If you can live with
the the tiny edge
the Optoma has on
the Mini for 480p upscaling, throw it out. If you can live with actual 480i processing and not
the 480i-CRT emulation
of the XRGB-3, throw it out.
The only remaining point would
the Mini's missing VGA processing. If you want
the scanline processing through
the Mini you have
to use a VGA
to component transcoder. If you don't need scanlines you can use VGA
to HDMI before
the Mini. Both ways it's easier and cheaper than keeping a whole different processor on hand just for VGA.
(Or you can do: DC/VGA > SLG > VGA2HDMI > MINI > TV)
