Frequent short sound drops and picture freezes in cable TV

lasts a few seconds - backing up shows that the loss is captures in the VCR. Mostly this is affecting WTTW 925. I've replaced coax and splitter. Signal strength is good per Xfinity. Happened 12 times during a one-hour show. Didn't happen at all on another channel.

user_ekwy9z Is this happening on a specific show on WTTW 925 or different ones as well?

Many different shows. And it was WTTW 915 - my bad. I tried to cancel recordings on 915 and move to WTTW 1011 - on-line research suggests this is a more robust signal, but the DVR diverted back to 915, probably because it's looking for a specific title, not a channel.

When watching live we can try 1011 but that doesn't really solve the problem.

Were you able to verify that channel WTTW 1011 does not have the audio issues? Have you tried making sure that you have the HD preferred option is selected in the series recording settings?

I have freezing and skipping problems with Chanel 915 which is WTTW, the PBS station from Chicago.  Rebooting the cable box does not solve the problem.  Can someone please help with his issue?

After keeping careful records, the recurring trouble is WTTW and 1011. Live or DVR, but not streaming on the app.  Replaced cables and splitter. Hesitating to contact Xfinity because I know the drill. I will have to deal with their bot, and hours later I will have to reboot everything, disconnect and reconnect all the cables, they will tell me the diagnostics don't show any trouble. I just don't have time to spend hours duplicating steps I have already taken. WTTW says they are looking into it. Not sure if that translates to action. Possibly it means the problem is in the queue and maybe there is a pattern, but maybe its Comcast / Xfinity. And why do I need two names?
