I got one last week, but haven't tested it thoroughly yet. It seems to be working well with the MII-12000. Nice clean picture, either resizable or fullscreen. I've tried the bundled software for a bit -- it is loaded with features, including timeshifting, scheduled recording etc.. Sound is transferred directly over the bus, so no loopback audio cable required. The card is WDM compatible and can be controlled by the Winamp tv plugin, so embedding it, eg. in RoadRunner shouldn't be a problem. The plugin won't give you any sound yet, but the author told me that directaudio will be supported in the next update.
I will post a more extensive review as soon as I'm done putting my system together.
