i bought a hero2 back in november. ever since i bought it, about 1 out of every 4 videos plays back with a purple screen with just audio. so whenever i am recording a video and capture some action i think to myself "man i cant wait to go home and watch the footage". so today i was at the track and rode the best i have ever riden in my life. and i filmed some great action. on the way home i couldent wait to see the videos. so when i pluged it up to the TV guess what, THEY ALL CAME BACK WITH A PURPLE SCREEN! i am so pissed right now. my dad just sent them an e mail about it. i saw the post on this site (in the product review section) that their customer sevice was great so i hope that is true. i attached a pic of the purple screen
