Yeah, but when the $ come in I want to use my new HDDVD

That's another problem. I can't find an SVDO card ( ADD2 is
the same thing? ) that supports component-out OR HDMI. There
are some DVI cards ( e.g. HP), but none support 1080i ( i.e.
1920 x 1080). They all seem geared for computer monitor
It's disappointing that Intel has designed and promotes this
chip set for a media box ( and by the specs it should be
great), but there's no way to actually use it.
