Thanks for the responses guys! You are correct, @AGuyWithAComputer. However, the problem is, if that version is available for downloading and I select it (1920 x 960), it tries and then after some times, switches to 720p and downloads it. I am continuously facing this issue only with AP. NF works just fine for me. I tried downloading another title today from AP and it ended up downloading only a 49 MB video file.
@Mona, Do I need to open a support case? I really need this AP issue resolved for me.
