Hello

For real hd input I agree that the sdi card would be the right solution. But this solution also needs converting. (vga or dvi -> HDSDI) This might become quit expensive.
Imagine the computer that runs has a dvi output. This has to be converted to HDMI. Thats easy as the signal is the same. (just use a DVI->HDMI cable)
I just worry about the cat. Will it recognise the cannopus?
Maybe Richard knows?
