Advertisements I'm not sure why I never converted my old TiVo files to MPG, but I didn't. I no longer have a Windows computer. I now have a M1 Mac as such I used tivo-libre to convert my TiVo files to mpg. That worked for almost all of them with a handful of exceptions. The error I got for all of these is: I also tried to use tivodecode-ng which I compiled for the M1, but that failed with: As a last ditch effort, I installed Windows 10 ARM64 under Parallels, but that was a lost cause as I couldn't play any TiVo file in that. I'm guessing because TiVo Desktop isn't compatible with ARM, though Windows 10 ARM64 is supposed to support 32-bit intel apps. Even if I got TiVo Desktop working, the Directshow Dump installer fails because it requires .Net 1.x which isn't available. Is there anything I can do to decrypt these files? Edit: I think I have an old Windows XP laptop with TiVo Desktop on it. Maybe that will work, but I don't even know if it will boot up.
