All answers are in reference to the MyHD card, I do not know about the others.
1. The card comes with a loop back cable. If you use the cable, then one connector goes to the VGA connector on the Video Card. A second connector on the cable goes to the MyHD card. A third connector on the cable connects to your projector.
The card has a distinct set of resolutions that the card will output. There is also a selection of VGA or RGB (usually called component but you need a breakout cable for the indivitual signals). The loopback cable is in one sense nothing more than a video switch. Switch one way, and the Video card output is sent to the output connection on the cable. Switch the other way, and the output of the MyHD card is sent to the connection on the cable. This is a long way of saying, you SHOULD use the same resolution on your Video card as you are using on the MyHD card. If your projector has the capability of sensing the video input format and automatically adjusting (my LT150 does) then you can run different resolutions, but it may cause syncing problems and can cause momentary flashing when switching between the video card and the MyHD output.
If your projector does not automatically sync with change of input, then I think you may have to make a decision, that being 1080i or 720P.
The current radeon drivers do not support interlaced video. If this choose 1080i, then you will probably either need to use older drivers that do support interlaced or a transcoder.
If you choose 720P, then you will need to set the Video card to 720P (possibly needing Powerstrip to get this resolution since it is not a standard computer resolution) output.
2. The MyHD card has 3 audio choices. Wave, which sends the audio over the PCI bus. Cable, which with a supplied cable connects from the MyHD to a spare Digital input on the sound card. SPDIF, which is a connector on the MyHD back to connect to a receiver that can do Digital decoding.
Some have had audio delay problems with wave and or cable selections. I personally just use 2 SPDIF cables, one on the MyHD card and one on the sound card. I then have to switch sources on the receiver. When this starts getting too painfull, I will probably get the auto SPDIF switcher.
Failure is not an option. It comes bundled with every Microsoft product
