-The best and cleanest way would be HDMI but for some reason, my Westinghouse HDTV doesn't play nice with HDMI input from my video card (overscan, poor PQ, flickering), a Sapphire Radeon HD4650. I sold the card as a result.
-The VGA out gives the best PQ to the HDTV, but I haven't tried a DVI-to-HDMI connection.
-The onboard sound output on the HTPC is limited to a stereo output, i.e., no digital out.
-The HTPC form factor is a slim (read: low-profile) Dell Optiplex computer that only has one PCIe x16 slot and one PCI slot. The PCI slot currently has a wireless NIC installed for Internet connectivity.
-Last but not least, my receiver (Yamaha RX-V663) does HDMI-pass through which I take to mean, it just passes the HDMI signal to the TV. I could be wrong on that part and it does decode the audio portion of the HDMI signal.

Given the above limitations, what is my best option? I was thinking:

1. Get a low-profile PCIe sound card (will it work in the PCIe x16 slot?) that has S/PDIF out that can be connected to the receiver via digital coaxial or optical cable.
2. Assuming I'm wrong above and the receiver does decode the audio portion of an HDMI signal, get another low-profile video card (probably HD5570) and connect the HDTV via VGA/DVI connection. Then connect the HDMI connection to the receiver. Set the video card to clone the display on both outputs.
3. Other.

this -- 663 does do HDMI audio

For HDMI input, you probably need to change a setting on the HDTV to allow 1:1 pixel mapping. Not sure what it'll be called. You might also need to adjust the resolution and refresh rate in your display driver properties.

I used to have a 47" Westinghouse LCD, could possibly be the same model (I had the LVM series, not the newer (at the time) TX series). I never could get the HDMI or DVI input to really work well, but VGA looked gorgeous. Granted, there are a lot more options in video cards now than there were back in 2007 when I was trying to do it.

Mine is the 42" VK series

Really? I'll have to try it out.
Yup, it had full HDMI implementation, including the lossless codecs. Only problem is that it compresses BTB and WTW signals on the video side, but since no actual media uses those values...

Yeah the RX-663 has the DTS-HD and TrueHD logos on the front (at least according to the pics I have seen). So go get a current generation ATI 5xxx series card. Personally I went with a 5750 fanless model so no extra noise, but it may or may not fit in your case (I have an Antec Remote Fusion Max case, which has a 140mm side fan and 120mm rear fan to give you an idea of height...none of those 60mm or 80mm stuff in the rear for me...).
