8 months ago, Charter installed a tuner adapter. I have had no problems until about a month ago. Now my Tivo freezes up frequently. Particularly annoying is when I have set a recording only to discover that Tivo locked up before the recording completed. This happens most often with live sports programs. I am really getting fed up since this problem defeats the whole purpose of paying for Tivo. I may have to bring the stupid Charter DVR down from upstairs and quit paying for Tivo. (My current software version is 11.0k.01-2-648) I also have lots of pixalation and missing channels.
