I have TiVo's Desktop Plus and have a 29 gb file that I want to save. Given the size of the file, dual layer bluray is my only option. I have purchased Nero 9, the Nero bluray authoring plug-in and a bluray burner but Nero does not recognise Tivo files. I either need to have help in converting Tivo files to something that Nero will recognise or help in getting Nero to recognise Tivo files. I did convert a file to MPEG4 on the facility within Tivo for putting a video file onto a protable player but the quality was awfiul. Any assistance would be greatly appreciated.
