If live TV is triggering the error, consider recording the content and then watching it after a short delay.
- Open the Guide in the app and begin recording the desired channel or program.
- Navigate to Recordings, select the recorded show or channel, and click Watch. Optionally, introduce a 5-second delay to the playback.
7. Cast Through Another Device or Use a Streaming Stick
Bypassing the Tvapp 00148 error on the TV version of the Xfinity Stream app can be achieved by casting from another device or using a streaming stick, such as Roku.
