About 3 weeks ago I started having a problem with my tivo when it would playback recorded shows. It has been having bad problems with skipping. When watching a recorded show the screen will freeze up sometimes for 2 seconds and sometimes for 2 minutes. It will also go to a black screen on occasion. The freezing/skipping will take place at least 10 times while playing back a 1 hour show. Sometimes it all adds up 15 mintues of freezed/skipping screens during that time. On other occasions it will freeze up and then restart the program back to the very begining. This is quite frustrating and I have no idea what causes this. When I watch the same show in real time/ live I never have any problems with it skipping or freezing. I hope somebody can please help me!
