This has happened just a couple of times on different channels. I have a scheduled recording, so sometimes I'll go into TIVO to start watching the program from the beginning, while TIVO is still recording. What has happened is that TIVO did not record anything. The screen is black, and the record indicator shows no recording is taking place. I jumped back into live TV, and my program is being aired, but TIVO is not picking it up. My question is; Is my TIVO unit (XL) starting to develop some problems, where I might have to replace it? Or, is this just a computer glitch that happens once in a while for no explainable reason. Hope someone can give the heads up as to why this is happening. Thanks
