If I get a DirecTV HD Tivo...

You have to run cables. There are no wireless HD signal transmitters other than the television broadcast towers. Component video cables are cheap is you make them from RG-59. Long HDMI cables are very expensive even from the discount cable stores. Don't even think about using Monster brand HDMI cables.

A 100 ft HDMI cable from monoprice runs just under a hundred bucks. 25 foot cables are in the $30 range.

Component cables are harder to run as you need three plus audio (optical or stereo) meaning 4 to 5 lines. And aren't that much cheaper (a 5 line 100 ft cable is in the $80 range).

Fifteen 50' cables (component video plus R/L audio x 3) was $80. 1,000' of RG-59 and RCA ends all from Ebay.

Not exactly what the OP is looking for. He wants HD from his receiver wirelessly transmitted to his TV. No mention about streaming HD from a PC server.
