Discusion of this problem occurs at least once a month!baum001 said:Having visited this board and visited TIVO's site I have never seen this.
The Tivo units without DVD-RW record in a non-standard format optomized for playback on a TV. The MPEG encoder is hardware so it can't be changed.
To make the DVD-RW units work Tivo had to record in DVD compatible formats. The Tivo box does not have enough processing power to convert between formats.
I have a combination of units and have my Humax connected to the Digital STB, typically I know if I'm going to save a program to DVD and can schedule it on that unit, otherwise I schedule recording to avoid conflicts and based on who will watch. Transfers back and forward between the units work both ways. It's just saving to DVD that is a problem.
