No, you would need an external dvd drive for your computer. Assume your computer does not have a dvd drive. You can pick one up at Best Buy for around $30.
There is no LED display on the front of this recorder. However, if you use the display key on the remote it will provide all of the information you need.
Upconverting means scaling a standard-definition image to fill the screen of an HDTV. It doesn't make it HD but helps fill the screen without making the image look too pixilated.
No..this will NOT play Blu-ray disc's. It is an excellent player however it will play other regional DVD and CD's. MP3 will play too... Excellent value overall. Easy to operate as well.
