slow FPS caused by auto exposure?

Greetings and salutations;

I've been banging my head off Cheese trying to figure out why I was 
getting slow FPS rates across the board.

On a whim, I installed guvcview and tried to fiddle around with some of 
the settings and stumbled on a fix for a problem that's been plaguing 
Cheese for way too long;

Under Windows 7 I noticed the auto-exposure setting for my camera was 
causing performance issues, so I decided to fiddle with them in guvcview.

While in guvcview, I selected "Manual Mode" from the drop-down in the 
"Exposure, Auto" setting then "TAB" selected the next option from 
"Exposure Absolute".

The "Exposure Absolute" was set to "156". I used my right arrow key to 
bump it up to "157" then back down to "156" and presto! my frame rates 
are a solid 30fps at a resolution of 1280x720, with normal exposure.

I quit guvcview, booted back into Cheese, and Cheese now works 
flawlessly-ish.

Not sure why or how this worked, but maybe it will help others who may 
be experiencing the same type of issue?

At any rate, now I just have to solve the audio sync problem when I 
record. :)

Thanks for making Cheese. I'm one step closer to being perfectly happy 
with it.
