user: a number of recordings on a new, almost empty DVR are unplayable: “Unable to play the selected program. Please try again.” I also get an error on the FIOS Mobile app. Other recordings work fine. Help?
agent: Help as arrived! Are the recordings that will not play also from 11/16?
user: Looks like 11/16 and 11/17 at least. Have had the STB only a few days.
agent: Thanks for confirming. Can you please reboot the cable box and try to access the recordings again? If you have not already tried this.
user: Just did! I unplugged and let it sit for ~30 seconds.
agent: As we are having an issue with DVR viewing could you reboot the router and then your cable box.
user: Ok! Done! Er, done - still jacked up.
agent: Please follow and DM us.
