Can't See Videos on Snapchat?

[TheyCallMeMini]

I have an LG Optimus S. Snapchat works just fine on it when I send/receive pictures, and I have Snapcapture so I can keep the pictures/videos. My friend sent me a video today, which is the first video I got on the app. It wouldn't work when I checked it on Snapchat, and it won't work on Snapcapture or in my gallery. :-\ Is there any way I can view it, or does anyone know why I can't?
