Does anyone know when a show is transferred to your computer, is the file the same as it was on the Tivo? I am especially curious with HD programing. If I transfer a show to my computer & back again, is the file the same as the original? I want to use my computer as storage when my Tivo is full. I already have a 750 gig external drive connected, but I can foresee needing more space once the fall season starts. I know that TTG & TCB are not available until November, but with the number of shows my wife & I are planning to record & the amount of time that we have to watch these shows, the Tivo should be filled up by then.
