The Tivo Slide shows up as 6 HID devices, 2 of which seem to grab the majority of the non-keyboard buttons (I use the keyboard plugin for those). Here's a picture, for those not familiar.

Now, when I hit the Guide button on the slide, it generates the scan code for the guide button on MCE remotes. Win 7 sees this and launches MCE automatically. No matter what. Can I disable this functionality somehow, so that I can use EG to manage that button? I'm shooting for using the color buttons as modes to control different devices (yellow == MCE, blue == Tivo, red = 360, etc.) and I don't want the guide button to do anything to the HTPC when I'm in the mode for a different device.
Any thoughts?
Also, I can't seem to get the Clear button (bottom left corner of the top part of the slide) to generate an event in EG at all. Has anyone done this successfully yet?
