Here you can compare the quality, on the left the old trotitube, and on the right the new. In first the size, it's bigger and 16:9, the video is encoded with the h.264 codec and AAC for audio. Videos are not resized, it's better for the quality and the full sreen.
Don't load much videos in the same time, if not you'll have to wait the end of the loading, watch the difference, and the sound too, it's realy sync now ! Tell me what do you think about on the SR forum. Thanks.
