Two of these were used for a short in-wall run. The other two were used as a stopgap until I source some longer v1.4 cables; they run directly from my Blu-ray player to my HDTV.
I can't yet attest to the performance of the cables I used in-wall, but everything seems to be working just fine on the BDP-to-HDTV setup. 3D movies play perfectly, and that's the big concern with v1.4 hardware.
The local electronics store wanted much, much more for the same quality cable.
