Mark has an old Windows 7 / XP machine with Windows Media Center and is looking to repurpose it. Mark is wondering if he should pull the hard drive and install Linux onto the drive and use MythTV DVR application on it? Leo says that it should be fine, but warns Mark of using the machine for more than just a DVR machine. Leo says that there are risks using an XP machine since there haven't been new updates for XP machines in some time, it could be infected with viruses passively when going online. But with Mark installing Linux onto the hard drive and him having a router, there shouldn't be any problems with Mark's plan.
