I tried to schedule a recording to start at the next hour , and it did n't . The TV schedule was fine and thought it was recording , but the DVR had not received this message . The FiOS DVR help screens were 100 % useless , so I poked around online and found the only suggest was to reboot the DVR .

Question: What may be the reason their show was n't recorded ?
Answer: They did n't schedule it for the right day .They do n't know how to use the DVR .They just got the DVR and never read the manual .There 's something wrong with their DVR .
