The last week or so I've been having problems where I start to play a PTAT recording and it only plays the last 2 minutes. It will let me rewind, but it turns out I've got the wrong recording I'm rewinding through. Not just from a guide mistake, but the wrong network. It's like the index of recordings somehow got messed up. Another point is that these are recordings where I've saved the series and I'm looking in My Recordings. Is there a way to have it rebuild the index?
