I seem to remember that for a long time I could schedule a program to record and end recording "one minute late" so as to not miss the next week previews. If there were another recording programed right after, the second program would simply start one minute late without problem. Now if I schedule a program and add one minute, one of two things happen: either the program will end at the scheduled time without adding the minute, or in some cases, the extra minute will be recorded as scheduled, but the next scheduled program will start up to three minutes late. Any ideas??? This is very frustrating!!!
