I've only tried those HDMI-to-CAT5 cables once, they were fussy and rely on good quality cabling (ie, shielded CAT5e or CAT6). You might as well spend the money on a good quality HDMI cable that you KNOW
will work, rather gambling on some non-HDMI-certified hardware that MAY
Bluetooth controllers are fine. I suggested the USB hub on an extension for a few reasons:
- You're already running an HDMI (or CAT5e) cable anyway. Why not run two at the same time for almost no extra effort.
- Bluetooth hardware is more expensive, unless you already have it. Do you have a bluetooth keyboard and mouse?
- You can plug a usb stick into a hub and download photos, play movies, save files connect your smartphone, connect the play & charge kit for your controller.
Essentially, I used to do this in my own living room when there was no space for the HTPC near the TV. I started off without a USB hub and in the end I bought one and ran it under the carpet before screwing it to the underside of the coffee table. Everyone thought my house was awesome just because they could play movies and charge their phone from the coffee table
The reason I suggested the XBox pad is that it has good windows driver support. Most games recognise and explicitly support the XBox360 pad and come up with an XBox360-specific overlay for it automatically, replacing "press enter" or "press e" messages with "press start" or "press (X)" with the correctly-coloured XBox button icon.
I've never seen a PS3 controller do that, nor any other third-party controllers. Sometimes the third-party controllers bring up the XBox360 overlay, but why buy an imitation when the genuine article is good quality and affordable?
