my mini is due to arrive from TiVo today and I just realized it has no optical or coax dig audio out. My kuro plasma tv does have optical out but won't passthrough HDMI Audio via optical. Room is setup to use 5.1 Logitech z5500 sound system which has spdif but no HDMI input! So now I have to buy a HDMI switch with optical out to make this thing work? How much will this cost? I need to decide quick if I need to refuse my TiVo order and just run hdmi/optical cable to my second room and just wire both my tv's from the same xl4.
