I replied in PM but just to update the thread:
Two years later and my original setup still works just fine. I use it every single day, in fact - we watch most of our tv (HD included) downstairs on our two LCD's and the Cat5e is what connects them.
I only ever had the one problem with one of the receivers (it lost the signal for blue) and they fixed it and had it back to me within a week. If you're looking for HD and SD component video and audio over Cat5e this is still the best solution around.
The only suggestion I would make is that A)They provide a way to transcode optical, instead of Coaxial, for digital connections - it's next to impossible to find an AV receiver that offers Coaxial digital out
- most just offer in, and optical out. You can buy transcoders to get around this, and I have, but it's an extra expense and works clunkily, to say the least.
B) Make the same product only HDMI over Cat5e/6 instead of component. By same I mean an Amp that can take one input (and be daisy chained for more, as with the current product) and sent it to two receivers, including the built in IR transmitter which imho is one of the best features. And of course keep it reasonably priced
All current HDMI/Cat5e/6 transceivers are one to one, expensive as all get out, and don't include IR relaying.
