I guess it should come as a surprise to absolutely no one, that Mac’s have been serving up dual duty as personal computers as well as entertainment appliances, for some time now. One user of just such a setup host’s some very informative pages on the subject. The original page My HTPC page lays out her requirements and goals for a ‘MacHT’ while a second more extensive page serves as an HTMac FAQ.
The second page in particular is geared toward one of my main goals with the Mac Mini, DVD playback through a ‘TV’. Have a look they just might be able to answer some of your questions about ‘Mac’n’ your home theater. Sorry couldn’t resist the pun.
While we’re on the subject of Mac’s as entertainment centers, macteens ran an article back in August on how to record high definition programming from the popular Motorola DCT-6200 HDTV cable box. It’s a seriously in-depth article and should provide just the info needed, for recording hi-def video from the Motorola box to your Mac.
