Possibly a stupid question, but:
If a receiver doesn't have HDMI input does that mean I can't, for example, have audio taken from my TV/PS3 to the speaker system?
Looking at a used Samsung Ht-twz412 for $150 and the most common review complaint is that it doesn't actually have HDMI input...
Optical out of PS3 to receiver, not sure if your TV has optical out.
