I'm using a Hauppauge WinTV-HVR-1600 model 1199 that "works" but only in an odd way. This card is listed on the Church site as one of the available options so I assumed it work work correctly.
First, I can't get it to work directly in windows media encoder (WME). And, if you try to get it working in WME, it seems to cause problems with the meeting house webcasting (MHW) software.
To get it working the first time, I had to install the hardware, drivers, and software from Hauppauge; and install WME & MHW. Then I had to UNinstall and then reinstall WME & MHW. After the reinstall, using the card in MHW worked. However, when I tried to get the card working in WME again, it broke MHW (everthing was in black and white). I rebooted with no improvement. I had to launch the Hauppauge WinTV application (and then exit) to get MHW to again see the video in color.
Another issue is that you can't get audio into MHW via the HVR card. There is no option to use that as an audio input for MHW. I have to use the computer's built in audio input (line in) instead. I was concerned because of the possible sync problems between the video and audio. However, it appears to work correctly (be in sync).
