I am a video editor who uses Final Cut Pro every day. I have recently taken up a habit of creating my own movie trailers from existing movies and messing around in other aspects of editing just for fun. However, I really want to get my feet wet with editing basketball games shown on TV and creating a montage of PS3 game footage, all in HD. I have seen products out there for Mac that allow you to record and watch live TV; however, I already have an HD-DVR cable box through Time Warner cable and I record all of my programs on there just fine. I just want to find out how I can import/capture this footage to my computer if I were to play it back on the TV. The same goes with my PS3. I'd like to be able to play through a game and have all of the footage capture to my hard drive on my computer. I have an iMac 3.06 ghz Intel G5 from May 2008. Has anyone ever done this before? Price really isn't too much of an issue (although anything over $500 might be a little much) so ANY suggestions would help tremendously. I basically want to capture in a way so I retain the true HD aspects of the HD-DVR box and PS3 and not lose any quality upon capturing. Any suggestions would be greatly appreciated.
