I know you can't record a show transferred from one Tivo to the DVD unit but how about a show transferred from the DVD recorder to a regular series 2 unit and then back to the DVD recorder? I have an upgraded standard series 2 unit and a stock DVD recorder unit and if I could transfer shows back and forth and still be able to record it would keep me from having to upgrade the capacity of the DVD unit also. It would seem to me that if this isn't possible then the video format isn't the only reason you can't burn transferred shows. I'd try this myself but I'm currently waiting on my Tivo wireless adapters and I'm impatient. Has anybody tried this before?
