Hi, i don't really know about using vga to hdmi converter, but i capture from hdmi source of one computer to another or to the same and capturing is fine. There might be an audio issue, though with your vga to hdmi converter, from what i read in these forums. HDCP doesn't seem to be a problem i can capture anything from the source computer. Color space isn't a problem that i know of the default setting should work. For input resolution, the roxio capture software will not start in less than 1024x768, however you can change resolution once program is started in capture mode. Also, something weird but cool, if your resolution is changed to 1280 x720, the program captures at 59 fps.
