I have had great experiences with generic cables.
All the cables that came with the media playerseg Dune, Yangxi HDPro, and a really cheap RMVB player.
Also cables that came with the PS3, Panasonic Plasma TV and one I bought from a computer shop.
The longest one at 45 feet, is from Monoprice, size is 24AWG and it works right away with my projector.
So long as the connectors are ok and the wires are not crimped, I believe the 101010...signal will get through.
However, if a branded HDMI will give me greater resolution, color depth and clarity with a deeper and wider soundstage, I am willing to try it.

My hypTv uses the same freebie cable and it works just fine.
In any case, spend your money as you see fit, after all, the satisfaction is immeasurable.
