Web Stream Portal: In-Progress DVR Recordings Disable Fast Forward (Metadata/Duration Bug)

Over the past week, I have been unable to fast-forward in-progress ("in-flight") Cloud DVR recordings when watching via the web portal on Windows 11.

The Symptoms:

• The Fast-Forward / Skip Forward button is completely disabled/greyed out in the web player.

• The scrub bar registers as filled to the end (2:01:30), locking the playhead and making it impossible to seek forward through commercial breaks while watching behind real-time.

• Looking at the Saved Recordings list, the metadata calculation is clearly broken—one recording displays an impossible duration of "3625min left" instead of the actual remaining broadcast time.

• Once a broadcast concludes completely and converts to a static Cloud DVR asset, playback and forward seeking return to normal.

(Attaching screenshots showing the greyed-out fast forward button / pinned playhead, as well as the '3625min left' metadata error).

Troubleshooting Already Completed (Issue Persists):

• Tested in both Google Chrome and Microsoft Edge on Windows 11 (identical behavior in both).

• Cleared all site cookies, cache, and local storage data for xfinity.com.

• Toggled Hardware / Graphics Acceleration off and on.

• Attempted keyboard navigation shortcuts (Right Arrow, L).

• Ran a "Sync DVR" command on our physical X1 equipment.

Crucial Detail: This issue is isolated to the web browser player. Playing the exact same in-progress recording on the Xfinity Stream iOS app works perfectly—the live buffer is recognized, scrubbing is fluid, and skip controls function normally.

This points directly to a manifest/metadata parsing bug in the web player rather than a client-side browser cache or network issue. Could an official Comcast/Xfinity representative please escalate this to the web platform engineering team?
