what sd card are you guys using in the hero 2 and havin success with? I just have a sandisk 4gb and when i plug it into the computer to watch it the video skips

Have you tried saving the video to your computer first? My thinking is the SD cards have to be high speed for video and you simply may have an interuption in the stream due to the speed of the card not being able to supply data quickly enought to make a solid stream of data. Try saving it first, before getting another card. If you do need another card try to buy as fast spped as you can afford.
