HDMI switching only is actually a pass-through function.
HDMI processing comes @ a higher price, so switching only provides the ability of the AVR the ability to handle an HDMI source such a Blu Ray player. The HD video Out from the Blu Ray goes into the AVR via HDMI and then out to the video display via HDMI, while the audio is handled either through S/PDIF (coax or optical) or analog.
Now HD video and audio are switched together, there will be a slight drop in the audio quality but the $ cost of the AVR will be lower and more competitive if one is on a tite budget..
