Hello all! I have an 50 Plasma TV. Also have Comcast Digital HD TV Service. I would like to record my shows that I watch on my TV. I have a DVD recorder, but I want 1080p or 720p quality and I don't think the DVD recorder can handle that. Is there an alternate solution? Like a several hundred Gigabyte external TV Recorder that I can hookup and when it's done recording I can transfer over to my PC? Any guidance is deeply appreciated. Thanks!
