two things i saw:
1.) you are telegraphing and finishing hyzer.....from a technique standpoint this is good....if you want to throw hyzers
http://www.discgolfreview.com/resources ... hing.shtmlcheck that link about shot telegraphing/forecasting...it may be a bit advanced but i still think it is good info....even from the still that rehder posted of you, you are showing hyzer....this maybe part of your early release issue
2.) depending on how far you truly throw, the star eagle may be the wrong disc for you....the star is the Eagle-X which is mad stable....i even have had weird release issues with dx eagles.....but that may be a fault in my mutant form
and to echo what the others are saying you are swinging your arm around and not pulling through....and lean into the throw more to get your weight forward.....masterbeato video and right pec drills will get you on the right path
also when you are making your throw don't grip the shit out of the disc....just hold it like an egg using your preferred grip method....when you get to the hit your hand will automatically grip the disc harder and you'll get good rip
i think that's all i got right now
