I have a Humax DVD recorder, DRT-400. I can record programs to the TIVO without problem. I wanted to transfer a movie from HBO I recorded to TIVO to a DVD disk. The program recorded correctly to the hard drive. I wanted to transfer the movie to DVD disk using the Humax DVD recorder (built-in). The recorder indicated that the DVD was burned correctly. All I got was a black screen with no audio or video. It would not play on the Humax, any other DVD player or my PCs DVD player. I reburned x2 with the same result. Then I recorded a program (football) off ESPN and it recorded and was able to be transferred to a DVD disk using the Humax with no problems. Does anyone have any idea as to what I can do to record movies to the Humax DVD recorder? Thanks!
