This is a nearly perfect product. It worked first time I connected it up. Antenna into DVR and out to DTV converter, then on to TV. This allows viewing one channel and recording another. It has internal digital tuner, can record shows from different channels, and has a very nice menu to do so.With this box, you can record one show and watch another simultaneously, a point they don't stress very much. Can record only one at a time, but that's a minor flaw. It is easy to use and produces great output, both video and audio.Unlike some others, it doesn't need cable, dish or other subscription. TIVO costs $13/month, this one has no such requirement.I wish they were more available and advertised more. I did quite a bit of a searching to find it, but have already recommended it.Recorded shows can be saved to DVD for future use, or recorded directly onto hard disk or DVD. At lowest resolution, it can record 200 hours, and picture is still great, much better than from VCR.I cannot recommend it highly enough. And I am glad to see someone (Philips) recognizes that not everyone is being held hostage by the cable/dish providers.
