No go for FLV format.
I got confused a week or two ago, blaming ogg support update (sorry for that one!) for my inability to play 360p FLV's which is smaller than what you are trying to play.
KMPlayer was able to play the 360p FLV though it's laggy and the audio and video are not in sync.
cuteTube will download the video in mp4 format, it's one of my favorite apps.
