I am a little concerned about reimaging my Tivo HD. I started the process last night and downloaded the attached text Mfsinfo.txt file from WinMfs (See Below) which indicates that my version is Software: 11.3b10.2017.10.11-1506-01-2-Z-663 this is the latest version as I understand it and I think it was assumed that my problem was due to the Software: 11.3b8 revision. I just do not want to lose all my previous recordings. At the moment I am downloading them using Tivo Desktop
