The thing is its not a problem of the TV Streamer... The problem is that IE reads incorrect or in 'heavy" way the tables coding, which is used on most webs... Especially if this table code includes flashes/streamers...
But IE 8 already solved this problem...
And yes IE 7 is the most popular browser... That is why many flash/video sites with the new (compare to IE 7) coding put announcements for users to download Firefox... Also Firefox streams videos better (correctly that is why faster)...
