I have noticed an issue when viewing recorded shows from a mobile device or desktop where the show is 8 minutes shorter and has many hard cuts removing dialog from episodes. All of the shows that I have noticed this are on the CW channel 2.
there is a known issue that affects random customers for random amounts of time. It appears that during peak times some servers are at over capacity for programs to be recorded. The errors cause the servers to move customers around to less 'full' servers over time.
