Is most SVGA cable rated for safe use in walls? (i.e. CL2/CL3/etc) I'd like to run an SVGA cable from my HTPC to the projector near the room of the theater. This would require running the cable up one wall, through a drop/suspended ceiling, and then dropping it back through the ceiling near the projector. Is it okay/legal to use any SVGA cable for this?
