Apologies its taken so long for an update, we're right in the middle of redecorating the place so am very busy at the moment. Also its taken a long time to get to where I am with the matrix now, I've had to do some extensive testing having got particularly unpredictable behaviour at first. One minute things would be working and the next they wouldn't. I've actually come to the conclusion that I have a faulty HDMI input 2 on my matrix since it never behaves the same as the other HDMI inputs (mostly it doesn't work). Anyway when I have a moment I'm going to get in contact with Joe at TMF about this problem and see what he thinks. Lets ignore the problem input 2 for now and I'll try and give you a bit more info (assume that I've used different inputs for the below)...
So all the cat 6 has been installed now and I have the kit configured as follows:
Virgin Media V+ HD Box -> Matrix Input 1
Acer Revo/XBMC -> Matrix Input 3
Matrix Output A -> 5m Cat 6 -> Receiver -> Samsung 40" TV (Lounge)
Matrix Output B -> 20m Cat 6 -> Receiver -> Sharp 22" TV (Kitchen)
(I also have had a 10m cat 6 run installed to the main bedroom but I've yet to buy a TV for this room yet)
If I had to summarise if everything is working as I'd had hoped, unfortunately the answer is no. It nearly all works however there is one exception: the Revo/XBMC refuses to show on the Samsung TV over the cat 6 connection at 1080P. It does work however if I use a 720P resolution or when the Sammy TV is connected directly via HDMI to the matrix and it also works at 1080P on the Sharp TV in the kitchen over cat 6. I've tried all manner of things to try and work out what the problem is, I've switched cables/receivers, the particular input/output the devices are connected to, but the issue always occurs with the Revo/XBMC over ethernet to the Sammy TV. Very frustrating. I'm still working on resolving this.
In my travels I've noticed that the order in which you switch the kit on is quite critical, but I think this has something to do with the fact I'm using the "Mode 1" EDID setting at the moment (I've yet to try anything else as of yet). Having tinkered with the matrix I've come to the conclusion that in this mode the matrix memorises the EDID configuration (for a given input) the first time a sync/source device handshake. So once this configuration is memorised even if another sync device is switched on or the source device is restarted its EDID settings aren't considered. This might be a good or a bad thing, I've yet to decide.
The following example might help explain the "memory" when using mode 1... if all is powered off, then I power on the matrix, followed by the Virgin box, then the kitchen receiver & the Sharp TV (so note its the virgin box that EDID handshakes with the Sharp TV first), finally the lounge receiver & the Samsung TV is switched on, I don't get any sound on the Samsung TV. This happens every time (provided I'm not using HDMI input 2 lol). Powering off & on the Virgin box and/or Samsung TV and/or Sharp TV doesn't resolve the issue. Whatever sound configuration that has been chosen (and doesn't work with the Samsung TV) has been remembered by the matrix. (So when I am powering on the matrix now I have to make sure the Samsung TV is the first to communicate with the Virgin box to get the sound working on all TV's).
However if I do exactly the same as above with the exception of powering on all receivers before the matrix everything works ok including the sound??? Perhaps the virgin box is just handshaking with the receiver alone before any TV is switched on???
In addition to this, I did on one occasion manage to get the kit into a state whereby the Samsung TV would display the output of the Virgin V+ box for about a second, then display static for a second, then black for a second and then repeat (the Sharp TV is off in this scenario). Even when I turned off & on both the Samsung TV and the Virgin box the result was the same, again suggesting that the whatever problem was occurring had been memorized by the matrix. Once I powered off the matrix itself and started again this issue resolved itself. (No idea how I got things into that state, I haven't seen that again).
Interestingly however even in "mode 1" sometimes if you are watching on one TV and you power on the other (to view the same source) the first TV will go black for a second or two suggesting that there is some EDID processing going on???
I think mode 2 behaves more like I would have expected from the matrix. That is; each time a new sync device comes online for a given input it will re-evaluate the EDID of the source and all sync devices connected and make a conscious decision about what EDID settings to use. But as mentioned earlier I've yet to try this setting.
There's plenty more stuff for me to try, hopefully there's a solution to my Revo/XBMC & Samsung TV issue at 1080P, getting this sorted is critical for me. Plus hopefully I can get this problem HDMI input 2 sorted or if not get a replacement matrix.
Oh, I do have one question... does anyone know what the "Smart Scan" setting is?
