Hi Mac guys and girls, I have a mac pro (4x3GHz 2007 version) which I hope to hook up to my TV (Panasonic 37 inch plasma) with a DVI-HDMI cable and an audio lead. I want to watch my movie collection on the TV. Now, I have several DVD rips (from purchased DVDs) ripped with MacTheRipper, but also several .mkv files which I've downloaded, including some 1080p files. Will HDCP be a problem here? From what I understand both the MacPro and the HDMI sockets on the TV support it, so what does that mean for the end user? Will it only affect "official" playback (like playing a DVD through the disc drive)? I'm hoping the TV will simply act as a second monitor for my Mac, doing everything my existing monitor does.... but this HDCP stuff is confusing and has me worried. Any advice before I drop £50 on cables? Many thanks, Z.
