cable box now only records 2 channels at the same time, once it would record up to 6 channels
do you have the x1 cable TV and internet service with at least one X1 set top box installed and working in the home?
i have triple play , arris xg1-a tg1682g,upstairs, downstairs cisco xid-c cx001ani
on the DVR use voice command 'about' and reply with rest of line after STB version. all but one xg1 has 6 tuners (oldest only 5). the xid takes a tuner to work from the total.
set top box xgi-a is an arris axo13anm
that is a version 3 DVR newest is ver 4. It could be a failure in the DVR, swap for new version 4. if still has a problem a tech will need to check for other issues like a missing POE (point of entry) filter where other possible neighbor's boxes are using your DVR's tuners.
