Whatever floats your boat, bro. This system is capable of completely unifying your AV setup, no matter which remote is used, that's the bloody point, but, whatever.
Why don't you get an IR blaster such as the USB UIRT, and have LinuxMCE actually control your AV devices instead of hacking them into the Gyration remote? You're doing it backwards!
Meh, does it matter? If you have a remote in your hand and press vol-up for example, does it really matter if the remote is sending to the TV or if LinuxMCE gets the command and forwards it to the TV? As long as you're only using one remote to control everything, and that remote isn't being carried from room to room, it seems like a fine solution to me. Ok, so maybe LinuxMCE can't automatically deal with inputs if you do it this way, but unless you have discreet input control on your TV I have found letting LinuxMCE handle that is more hassle than it's worth. If there isn't a template for your TV it's a bit of a hassle to setup. Then there is the cost and appearance factor. Why would anyone want to pay $50+ to have extra stuff near their TV and go through the setup just so they can press the same buttons and have the same results?
Or maybe I'm missing something?
That's how I have it setup, but some people have a more simple setup and if it works for them then it's not necessarily backwards. To be completely honest, the whole USBUIRT thing doesn't work well with my TV. The IR from the remote messes with the IR from the USBUIRT so volume control doesn't work. In testing I covered up the remote and USBUIRT receiver leaving the remote USBUIRT sending unit over the TV's IR receiver and volume works fine so I know it's interference. It's been confirmed by others when I first asked, so it's not just me. Plus using my GoMouse, volume control is fine. In my case, I'm doing it the LMCE way, but the more simple solution of programming the remote to send the TV vol control would work better. No, I'm not going to completely cover my IR receiver on my TV, the TV has semi-discrete inputs and LMCE gets all confused so I just use the TV remote whenever I want to swap inputs.
The problem comes down to the fact not everyone has the same hardware, some works well, some doesn't. Some people have complicated setups where LMCE really shines, other people have simple setups where doing something the LMCE way is more $$, more setup, and no additional functionality (or even less). Personally I'm trying to do everything by the book, but it doesn't always work out well as in my TV example above. Another issue is that IMHO, IR sucks. Now that I actually have a working LMCE setup, I will be trying to keep new purchases LMCE happy. Things like a supported TV and A/V equipment with serial/usb controls. Until then, I'm stuck making compromises.
