Yes, I eventually talked to tech support at Matrox, and they confirmed this.
I didn’t exactly follow the answer, but he said that some editor environments detect “overlay services” automatically to output to fullscreen. Other editors require a special plugin to support this output feature specifically.
Vegas is one of the editing envonments that requires a plugin. And because the plugin has not been made specifically for vegas, therefore, the card can’t let the HDTV serve as a broadcast monitor.
I don’t exactly follow this.
Someone suggested using linkplayer 2 to connect your USB HD drive with
your HD content to the usb port of linkplayer 2. That sounds doable,
but tedious during the edit process. I don’t exactly know what the typical workflow process is like (although DSE’s book on vegas 6 is on its way to me from amazon.com, so maybe I’ll know soon).
Other ideas?
