DVI signal booster, do they exist and do they work ? Hoping to go the Samsung DVD-HD935 via DVI-D to Sanyo PLV-Z2 but have read 5m is max dvi cable length for good signal transfer. Have noted on Amercian based forums people have used electonic signal amplifiers etc. I need to run a dvi-d cable circa 14m. If this is not possible what is the maximum length a good component cable can run too, if i switch to a Denon DVD2200 Thanks in advance. Chris L.
