Months ago I created a video player for my company. It uses a Video object, and typically plays back H.264 videos. All has been fine and dandy until we started producing larger, longer videos. When playing back a longer, larger video the playback will stutter until the video has completely loaded (even if it has already downloaded the portion of the movie it's currently playing).

I assumed there was a bug in my player, but after optimizing, tweaking and even removing everything except the code that loads the video it still stutters until it's completely loaded. I even tried re-encoding the video -- no luck.

As I said these are long, large videos so waiting until they are completely loaded isn't a good option.

Given that it doesn't seem to be my player, I'm wondering if this is a known issue with H.264 videos in the player? I'm running version 10.3 in Internet Explorer 8. The video in question is 640x360, 24fps.
