I lost my HD DVR due to the 12/1 firmware update. Since I rehooked up the new box I can't record remotely from the computer any more.
Do I have to reregister my remote account?
You probably have to go to the MY STB page on FIOS TV CENTRAL and there should be a button to refresh the STB list. After that you may have to re-enable remote DVR from the the TV CENTRAL page.
