Well when the video starts it oftens pauses the background music and the first couple frames get a bit choppy or it takes a lil while to start. The speech never messes up, though. I tries holding the speech to see if that would affect performance, but it really didn't.
Actually when you get all those sounds in there together it starts to get a bit busy, anyways.
I was considering using rederfix, but I wasn't sure how long that would take eveyr time I come back from a game. I'll give it a shot to see hwo it turns out.
If you need any testing done then I'm your guinea pig.
