Best HD AV Sender/Receiver (HDMI?)

[bellejt]

HDMI wireless is useless in house with metal in the floors.In my living room is only a suppoting beem because I took a wall down and because off that it is not working anymore.I have such an expensive system and only works on same floor.The remote is working through HDMI but indeed a second cheep box is better.If possible a simple sat connection to a disc and you have all you want.

PS : never tried the ones that are working trough electricity network (220 V) .Seemes they are fully working but would not take the test my own because they are very expensive to.Perhaps somebody else tried them.
