Leo says that the G-Box runs XBMC and it may be that he needs to run a plugin that will add a channel guide. Another issue is that guides tend to cost money. Leo recommends Googling XMBC and "repository," he'll find one he can install. Here's some places to look: XBMCHub.com, http://superrepo.org/, and XBMC's Wiki.
Pete would like to encrypt his hard drive so nobody could use his computer unless they had the password. Leo says the easiest way to do this is to use the file lockers that the OS comes with. Windows has BitLocker, and Apple has FileVault. He can turn them on in the OS. But some people don't trust them because they don't know if there's a back door built into them for the NSA. So open source options like TrueCrypt exist. Can he just encrypt folders? Leo says absolutely. He can also encrypt external drives.
Mark wants to create a media server in his home that he can stream throughout the house. Is there a server that works across multiple platforms that will allow him to go from room to room and remember where he was? Leo recommends Plex. It's based on the XBox Media Center and they've gone well beyond that. And XBMC will remember where he is.
Leo says that XBMC comes from XBox Media Center. It's a lean-back interface to navigate through and watch content. Leo says it really isn't legal or illegal, but like any computer, it can be used to watch pirated movies from bittorrent and other sources. Leo likes Plex a bit more because it's more polished, but XBMC is a great player.
So far, Edgar has been looking at the Western Digital Media Player or the GBox Midnight, which he can then use to make his HDTV into a smart TV or use with his Android Phone. Leo says that he hasn't used them, but it could work, and today's smartphones are more than up to the task with their quad core processor. Looking at reviews on Amazon, there's a high learning curve unless he's a serious techie.
