Fred, I don't have any long runs of HDMI but I am using the redmere cables from monoprice. They are nice and thin and flexible and work well. The longest I have used is 15ft and it works fine. I know they have more goodlier ones than what I use but if you buy from amazon you can pretty much return them no questions asked if it doesn't work out.
