I feel that inexpensive hdmi cables are fine for short runs but I just finished my basement and have 2 identical movie/gaming areas. Each has a pannasonic 65" vt30, denon 2312, Xbox, pan 210 bluray player etc...
1 system uses 3' hdmi cables (I'm talking $5-$10 each) to the receiver and a 6' to the plasma with absolutely no issues whatsoever. Including 3d!
My problem came with the second system which required a 50' hdmi run in the wall from the tv to a closet with all the components. So...I thought I'd play it safe and a bought and ran 2 different 50' hdmi cables with a cost of around $50 each. Each one exhibited freezing/dropout issues. I don't recall which brands they were but both were rated 10.2gps, Ethernet, in-wall, and whatever else the latest specs are. Needless to say I was pretty pissed off since it is not practical to run another cable in the wall.
Since I already had 2 strikes I coughed up $350 for a Monster hd1000 or some bs model number like that and have been running without issues for the past 3 weeks. It is still just running along the baseboards and will have to tuck it under/behind them at some point. While I'm not saying that monster is the only solution it was one that worked for me at that distance.
