Hi, I have uploaded a HD video to Youtube (1080p) and have been able to watch it on my ipad in 720p. Now, after a few months, I wanted to watch it again and now it will only give me the 240p version. The settings will not show any other resolution. When I look at the video on my desktop, I see all versions between 240p and 1080p are there. My iPad is connected to Wifi, like before. Bandwidth is 30Mpbs, so that is not a problem. Other video's play well on 720. My iPad is running IOS 6.0.1 Does anybody have an idea what could be causing this ?
