Wheres my shows

It only shows some of the shows that are recorded on my DVR. Wont load all the shows on my DVR just some and I had an episode where I went to watch it but it only showed first 15 minutes of it and said the rest wasnt there. Get home and the full episode was on my DVR so why wasnt it letting me watch the full one on here? Bug fixes maybe?
