I think I’ve stumbled across a bug. Today, the show “2018 Wimbledon Championships, Round of 16” was playing on ESPN and ESPN 2. While the two shows have the same name, they were actually not the same. I recorded both of them. It appears that I’ve ended up with one file flipping between the two channels every half a second or so.
This ends up looking like a heavily corrupted file, but I believe it’s two tuners trying to write to one file at the same time.
Admittedly, this is not a frequent occurrence where there are two different shows playing at exactly the same time with the same name on different channels, but this can potentially be an issue with some sporting events. For instance, this is actually going to be an issue again for Wimbledon on Tuesday and Wednesday of this week.
