Do you use the TiVo to skip commercials? Any time I'm using any streaming service the missing 30 second skip or "D" skip commercial break is what has prevented me from changing to any steaming service full time. I've tried YoutubeTV, Hulu LiveTV and Sling and they don't have a great way to skip the commercials from what I tried. I had Sling for all of the college football season since Comcast didn't have ACCN at the time.

The issue you might be having with the TiVo might just be a bad HD or if you are lucky a clear and delete all might fix this issue. If you have many unwatched shows you will not want to use the clear and delete all option.

Weakness will sell you a new drive and even do clone the old disk to the new drive keeping all your shows and settings.

I remember using MFStools and WinMFS to clone and expand my TiVo's in the past. WinMFS seems to required downloading form Archive.org https://web.archive.org/web/20150219190704/http://mfslive.org/forums/download/file.php?id=86

I also found a good writeup of on how to use WinMFS on Engadget.

If seems that DvrBARS seems to be the new program to use, but I've never tried it myself.
