Query: I learned not to skimp on HDMI cables

Works fine for most devices, but when I tried to use these with my AverMedia HD video capture card, one of them wouldn't work at all and the other one only worked in one direction (I had to plug a specific end of the cable into the card -- the other end didn't work). I know the card wasn't the problem because I tried it with a cable from a retail store and it works perfectly. Moral of the story: don't skimp on the cables you use to connect your expensive electronics.
