Tennis Channel Out of Sync

For a few months I have had an issue when watching The Tennis Channel, that after a few minutes the sound is out of sync. I have to exit out of my recording and resume to get it to be back in sync, which only lasts for a little while until it goes out of sync again.

Anyone have any similiar issues, even if its with another channel, or recommendations for what could be wrong? Or how to fix?

Thank you!
