I have noticed for the last couple of days by TiVo has been starting recording at the true start time. That is, it isn't starting 5 minutes early and fininshing 10 minutes late. A program from 8:30 - 9:00 is a 30 minute recording from 8:30 onstead of a 45 minute recording from 8:25. There aren't other recorings happening before and after either. The clock looks correct too. Any idea why this is happening?
