PROB: GoPro HERO Wide (non-HD) freeze issue

With my GoPro freeze issue, I tried different batteries (Duracell rechargeables 800mAh & 1000mAh, and even Energizer Ultimate Lithium) and different units (I'm on 3rd unit, thanks to GoPro's great customer support) with no success. The issue was with the 2GB SD card that came free with my purchase. GoPro recommends Class 4, so I got a Patriot 4GB Class 6 SDHC card today, and it finally works.
